Obituary For Kai Otto Wesener

Kai is survived by his parents, Jon (Jonathan) and Gin (Regina), his sister, Jade, grandmother Priscilla Umengan as well as numerous aunts, uncles and cousins, girlfriend Serafina McFall, pet cats Tiger (his favorite) and The Professor, and dog Milo.

Our son Kai Wesener passed away at the age of 17 years old on October 30, 2023.

Kai Otto Wesener was born on May 1, 2006 in Fremont, California. His name is Hawaiian for the sea and his middle name is from his grandfather of German descent.

He was a beloved son, grandson, brother and friend. Kai was an amazing, talented young man with a keen sense of humor, kind, generous and adventurous heart. His background included six years of gymnastics, mountain biking, rock climbing, skate boarding, and ran for the High School cross country team. He grew up loving the outdoors with his family and spent many trips camping, going to the beach, and hiking the Sierras. A seasoned traveler, he visited the Amazon, Ecuador, the Galapagos Islands, Peru, Costa Rica, Mexico, Greece, and the Hawaiian Islands.

Kai attended preschool at ABC Magic Moments, Sunol Glen School from kindergarten through 8th grade, then transitioned to Washington High School.

Kai was passionate about music, an excellent musician proficient on guitar, drums, bass and keyboard. He played the trombone in Band, and co-founded the first rock band, Bitty Smash, in his middle school at Sunol Glen. He wrote and produced his own music and eventually was selected at GRAMMY Camp 2023 by the GRAMMY Museum as one of 86 talented high school students from 71 U.S. cities across 22 states. He spent one week at USC over the summer to learn, collaborate, and train with his peers and recording industry professionals.

He had just released an album on Band Camp of music he wrote, performed and produced himself under the name bl4ck m4rket c4rt. He was planning to pursue a degree in Audio Engineering and Music Technology.

He was deeply loved by many and will be missed beyond measure. A Celebration of Life will follow in the near future.

    All I hope is that Kai's loved ones read these messages and realize the impact he had on so many people who he never knew would listen to his music. Rest in peace, Kai Wesener.

    Here from discovering Kai's music. I didn't expect it to touch me so deeply, his debut album is beautiful and full of heart and soul. I have shed tears for a kid I never knew, and I am so sorry for the loss of this lovely soul. Thank you for everything.

  • 01/17/2024

    I am so sorry for your loss. Losing a loved one especially one so young is devastating. I have found 2 scriptures in the Bible that has given me peace during my grief. They are found at John 5:28,29 and Revelation 21:3,4. Again I'm so sorry for your loss.

    i really enjoy Kai's music, and when i learned that he lived in fremont my heart broke even more. i have lived in fremont all my life and have visited washington highschool multiple times, i even have friends who go there. to know that such an amazing and talented person, who makes such touching art, passed at such a young age is awful. i have been battling my internal struggles with life and his EP really connected with me. i wish i could thank him. thank you.

  • 12/06/2023

    I have just discovered him. I was looking forward to getting in contact with him, to talk with him a little, just to have found this webpage. Heartbreaking. I haven't even known him, but I already feel like he was one of my closest friends. Maybe because he touched me thoroughly. May Kai rest in peace.

  • 12/03/2023

    I am a huge fan of Kai's music and I was devastated to hear about his passing. His music inspired me and a lot of other people, my thoughts go to Kai and his family and friends.

  • 12/02/2023

    He had so much talent at such a young age. It pains me to think of what all he could have created. Gone way too soon. Thank you for sharing with us your music while you were here, Kai. You will be missed.

  • 12/02/2023

    A brilliant artist who has passed far too soon. His music brought so much inspiration into my life. My thoughts and prayers are with your family. May he rest in peace. (Alive, Always)

  • 12/02/2023

    A very talented man. His work helped me a lot in the worst of places and when I happened to be scrolling through my recommended tab, was fortunate enough to come across one of his unreleased songs during a withdrawal. It touched me and still does after these few months, I wanted to say thank you, I'll continue to appreciate Kai and his work for as long as I have the rest of my life. Rest in peace.

  • 12/02/2023

    His music is absolutely beautiful and i hope he is at ease now.

  • 12/01/2023

    i met kai at grammy camp earlier this year. we only shared a lunch together but i still remember his smile and how he recommended a drum beat for one of my songs without me even asking. sending love and prayers.

  • 12/01/2023

    his music was beautiful

  • 12/01/2023

    I didn't know Kai, but I listened to his ep: Today I Laid Down. It touched me in a way that not a lot of music has. Rest in peace Kai.

  • 12/01/2023

    You will be missed Kai, not just as an artist, but as a son, and friend. I wish I had discovered you sooner, your passion will not go unnoticed. I hope you can rest easy now. Rest in Peace.

    Kind-Authentic-Intelligent. We love Kai so much! We are fortunate to know this young man, out of his 17 years, for over 15 years of our lives. Kai made my son be a happier boy, and he made me want to be a better aunt. I could easily say that Kai was one of Thorben's first true friends. With a unique way to speak, to smile and to laugh, Kai's sense of humor was so special, that it could easily make an entire room feel welcomed. All the memories together, car rides, hikes, runs, swims, tube-boating, plays, games, card gaming, Lego times, cars-truck toy times, nerf-gun teaming-up, bike rides, boat rides, paddle boats, surfing, homework together, school activities, band playing, first concert together, first girl-friend around, first dance, walks, camping, gymnastic awesomeness support-times, singing, rhyming, joke telling, board gaming, movie time, burp & farting times, rock climbing, tree climbing, mounting climbing, laud moments, quiet times, meals together, snacks, gatherings in Ca and in Hi, are already treasured in our hearts. I will never forget the way my son was everytime he was around Kai, and he would always make the same comment: "Another super time I had, thank you, mom". Kai was a fun-talented-smart young boy who already lives with God now. We already miss him, our buddy, so much. Vaya con Dios, mi hijo querido, rest in peace, sweet boy.

    I met Kai two years ago in my Sophomore year Chemistry class. The teacher had assigned lab groups for the whole first semester, and that's where I first met Kai. I still remember the sound of his voice and the way he looked. His brown hair touched his big brown eyes. He wore a cap, a yellow Jansport backpack, blue jeans, and Converse. He had rings on his fingers and bracelets on his wrist. Whenever our lab group needed help with a lab or assignment, Kai would always figure it out and help us. When we were uncomfortable using the Bunsen burner, he would be the one to step in and light the matches. Kai was very kind, considerate, charismatic, thoughtful, and outgoing. I didn't know him well enough, but I remember some aspects of him. He was passionate about music and fashion. He had a versatile taste in music and talked extensively about various artists he listened to. I remember hearing him talk a lot about Tyler, the creator. Kai was joyous and brought life to the empty classroom. You could hear Kai's laugh from across the room. His laughter instantly illuminated the room. You'd turn and see him sitting at a lab table, talking and laughing with his friends. Kai was cool; one thing anyone who knew him would notice about him was his sense of style. I remember sitting at the lab table and him talking with our group mates about the turquoise ring on his finger. That signature turquoise ring that you'd always see him wearing. I've always thought his rings were cool, and I liked how he expressed himself through fashion. After hearing the news at school, I remember that day in the evening, looking at the sunset. It was beautiful, pink, orange, yellow, and green at the horizon. I immediately thought of Kai. I knew that I'd never look at the sky the same again. I will always look for Kai in the sky, sunsets, and the stars. I believe he is looking down at us, too, from the heavens. Kai will forever live on in our memories and our hearts. I am deeply honored to have known such a beautiful, kind-hearted, and sweet soul. My heart goes out to Kai's family; you are always in my thoughts, and I am here for you in any way I can support you. Kai, I will never forget your kindness. Even though you aren't here, I will continue to listen to your music, support you, remember you, and honor you. School hasn't been the same without you; your teachers, classmates, friends, and family deeply miss you. Rest in paradise, Kai. We love you forever.

    i never met kai, but i would have absolutely loved to. i know of him through his alias bl4ck m4rket c4rt. in the small timespan that i got to learn, it's only showed me how wise the young man was and how bright he had shined. i just wanted to share that his impact reaches beyond any predictable conscience, he continues to teach people to stay onward regardless of where he lays. i only hope now that he knows that he did create a ripple in the deepest ocean, and i am watching it amplify every day.

  • 11/10/2023

    I never got to know Kai very well but I had numerous classes with him Sophomore and Junior year. He always shared meaningful opinions in English class and his smile and laugh was contagious. Sending prayers and love to your family ♡♡ Kai you're greatly missed and we wish you the best♡♡

  • 11/08/2023

    My son attended GRAMMY Camp with Kai, where I had the pleasure of meeting him and his mom. These young, talented, aspiring musicians quickly bonded. By day three, my son was hanging out at Kai's dorm each evening, making memories and music. Gin, please accept my heartfelt condolences. I am so very sorry for your loss.

  • 11/07/2023

    Kai was a close friend in middle school. He was so funny and was such a light to our friend group. I remember one day in sixth grade during math he could tell I was struggling and didn't hesitate to help me out. He was such an amazing friend and will be dearly missed❤️

  • 11/07/2023

    Kai was one of the most brilliant people i've ever met in my life. He was easily the funniest out of all of us in middle school. For the past year I've had a random quote of his from 7th grade as my twitter bio because of how funny it was. His mind was so unique and he always found a way to communicate himself in a complicated but beautiful way. I loved this guy so much, he will be dearly missed.

    My heart aches for the passing of Kai. Kai was the first person I talked to at Grammy Camp and I have never clicked with someone as fast as I did with Kai. We immediately connected on our love for underground music and indie rock as we walked with each other to class on the first day. After that first day, I remember leaving camp and telling my friends back at home that I had finally found someone that shared common passions and interests as me. As the week went on, we only grew closer and closer. I will forever cherish the memories we made together in the studio and the fun nights at his dorm after camp. I will never forget the late nights listening to Frank Ocean, Beabadoobee, and Charlie XCX on his laptop while discussing life with him and the rest of my Grammy Camp friends. We shared inside jokes and bonded over music each day. One memory I have of him was when I was in a room with him after camp one day. We were talking about his girlfriend and the topic of high school relationships. Love is a very important topic to me, and I ended up saying to him something along the lines of "I could never get into a high school relationship because I would take it too seriously and fall too hard." After I said that Kai looked at me and said, "Yeah, you seem like that type of person." This comment has stuck with me ever since. The fact that he could read me like that, despite only knowing him for a few days, shows how close we had gotten in such a short amount of time. Even though I was only able to spend a short amount of time with Kai, the time I spent with him was the best time of my life. He was an incredibly kind, talented, and down-to-earth individual. I don't have a single negative memory about Kai and he was always smiling when I was with him. Sending all the love and support to his friends and family during these healing times. Love you forever Kai, rest in peace. You will be remembered forever. May God bless you.

    I remember hanging out with Kai at Grammy Camp almost every day. We both wanted to study Audio Engineering in college and got closer by being in the Audio Engineering program together. I remember one night after camp, some people returned to his dorm to record a song. What was supposed to be a productive session turned into a group hangout filled with laughter and long-lasting memories. Kai was such a talented musician and kind soul. He will forever be remembered for the positive energy he brought everywhere he went and the creative musicianship he possessed. Rest in peace Kai. Your memory will live on forever.

  • 11/07/2023

    Your quiet light will always shine in my memory of unique musical souls I knew. You: the only student I ever had that loved Slowdive, and My Bloody Valentine. You were more than enough...genius silence, loud introverted expression and beautiful soulful sound. I will always light a candle for your soul on Oct 30th, through Nov 2nd...Angel sunshine follows you in the afterlife...Your name reminds us that spirit is Ocean and your emotion inspires us to livestream love in our hearts. May your friends and family find solace in your creativity. Your teachers LOVE you!!!! Blessed soul rest in heavenly peace! Much love to your family who created such a deep beautiful creative sensitive child - Julianna Danner-Vera

    I didn't get the pleasure of actually speaking to Kai at Grammy Camp, but I do remember sitting next to him at lunch one day..I remember him smiling at me, and I thought to myself that he just gave off really kind energy. His music is incredible and reminds me a lot of my favorite bands. He was a special kid and a true artist. Rest in peace Kai 💜♥️
