NEW YORK (AP) - Colin Kroll, a tech executive who co-founded the HQ Trivia app, has died. He was 35.
Law enforcement sources tell TMZ, Kroll's girlfriend called police early Sunday and asked them to check up on him after she was unable to get in touch. Cops went to downtown Manhattan to do a welfare check, entered his apartment and found Kroll's body in his bedroom with drug paraphernalia nearby.
The medical examiner's office will determine the cause of death.
Kroll was the chief executive of the trivia app, which live-streams short trivia shows to users and became popular after its release in 2017. He also was a founder of Vine, which was an app built around six-second videos, and worked for a period at Twitter.
