A U.S. Park Police officer shot and killed his wife and himself with his work-issued weapon, Charles County police said.
The husband and wife got into an argument Thursday in their Indian Head, Maryland, home.
Amid the argument, 46-year-old Jose Ramon Bumbray shot his wife, Brenda Jenette Harrison-Bumbray. Bumbray then shot himself, police said.
The couple's young adult son was in his bedroom, where he heard the argument and the shots, police said. He found his parents suffering from gunshot wounds on the floor of their bedroom and called the police.
Police arrived at the home on Fallen Timber Way in Indian Head about 8:10 p.m.
Harrison-Bumbray was pronounced dead at the scene. She was 50.
Police said Bumbray was taken to a hospital, where he was pronounced dead.
Bumbray was a U.S. Park Police officer since 2002, according to police. Police said he used his agency-issued gun in the fatal shooting.
The murder-suicide was the third domestic violence incident resulting in death or serious injury in the county this year.
"The first case we had this year, back in January, we have three young children who are left behind. No parents," said Diane Richardson, of the Charles County Sheriff's Office. "And then this case last night, I believe there were three or four children."
