CHESAPEAKE, Va. (AP) — Officials say a security guard is has been charged with second-degree murder in the shooting death of a 60-year-old man whose family says was playing Pokemon Go.

Chesapeake Commonwealth’s Attorney Nancy Parr said Thursday that Johnathan Cromwell has been charged with second-degree murder and use of a firearm in the January killing of Jiansheng Chen.

Police say Chen was sitting in his minivan in a parking lot when he was shot by the security guard after an altercation. Chen’s family has said the man was playing Pokemon Go.

Andrew Sacks, an attorney for the security company, said it believes the man acted in self-defense. Sacks said Thursday that the company continues to stand behind Cromwell. An attorney for Cromwell declined to comment.

James Broccoletti, an attorney for Chen’s family, said they are “very gratified” that charges have been brought.
