BATON ROUGE, La. (AP) — Baton Rouge police are investigating a murder-suicide.

Cpl. Tommy Stubbs tells The Advocate 37-year-old David Robinson was arguing with his wife about a divorce.

When Robinson tried to access a family computer Monday night, Stubbs says he discovered his step-daughter, 26-year-old Reagan Rowe, had changed the password so he could not use it.

Stubbs said Robinson shot his stepdaughter, then turned the gun on himself.

Both Robinson and Rowe were pronounced dead at the scene.
