WASHINGTON (Circa) -- TMZ reports HQ Trivia's co-founder Colin Kroll has been found dead after an apparent drug overdose.
Kroll's girlfriend called police on Sunday after she was unable to reach him. Officers conducted a checkup of his home and found his body next to drug paraphernalia in his bedroom, according to TMZ.
Kroll was the co-founder of Vine as well as popular mobile game app HQ Trivia.
In 2017, allegations of inappropriate behavior by Kroll were revealed in a report from Recode. During Kroll's tenure working for Twitter, he was accused of being "creepy" towards women. The publication reported at the time that this led to roadblocks as HQ Trivia was raising venture capital money for their app.
Kroll apologized in March for inappropriate actions “that made some people feel unappreciated or uncomfortable.” Soon afterwards, the app was able to raise $15 million in March and eventually even received funding from Disney. He was also named CEO of HQ Trivia's parent company as the app expanded beyond trivia into a Wheel of Fortune-like game known as HQ Words.
Recently, Kroll faced an HR complaint from an employee of HQ Trivia due to his "aggressive" managerial style, according to TMZ. The app was also suffering from declining viewership and went from being top 10 on the Apple app store to a spot between 250 and 500.
Police tell TMZ they believe the drugs involved are cocaine and heroin. HQ Trivia was expected to hold a Trivia Night dedicated to Spongebob Squarepants on Sunday but there is no word on if this is still happening.
HQ Trivia released a statement confirming the news saying, “We learned today of the passing of our friend and founder, Colin Kroll, and it's with deep sadness that we say goodbye. Our thoughts go out to his family, friends and loved ones during this incredibly difficult time."
