Evidence reportedly found on his mobile phone linked him to the murder in Texas, according to Bay Area publication the Mercury News.

Flower Mound detectives released a statement Tuesday night saying the suspected shooter of Mr Thane wore a helmet and jeans, and was thought to have immediately fled the area.

A Bay Area police official told the Mercury News the suspected killer set a propane tank on fire outside Mr Thane’s house to lure him outside, where he was then shot dead.

Police believed the pair knew each other through online gaming and are investigating whether it was related to a dispute between the pair.
