The Harris County Sheriff's Office says Hargrove lived in the home with his girlfriend, who he had been dating on and off for seven years. However, Hargrove was married during most of their relationship His wife, Sandra Hargrove, told ABC13 they separated in November after a 14-year marriage.

"He's still my husband," Sandra Hargove said. Hargrove said she didn't know her husband was living with a girlfriend.
