TAMPA — A woman concerned that she hadn't heard from her husband came home Tuesday to find that her adult son had killed the man and then himself, authorities said.

Juan Luis Hernandez II, 30, shot himself after first killing his stepfather, Michael Edward Kurz, in the family's home at the 42nd Street Apartments, the Hillsborough County Sheriff's Office reported.

Kurz, 59, died of "upper body trauma," the agency said.

Hernandez's mother, whose name was not released, grew concerned when she couldn't reach either man by phone, Sheriff Chad Chronister said. She left work about noon to check on them and found their bodies.

All three members of the family lived in the apartment together. The woman told investigators that there is no history of violence between the two and neither man has a history of mental health issues, Chronister said.

The incident is the latest in a recent spate of murder suicides in the Tampa Bay area.

During Tuesday's news conference, the sheriff said anyone struggling with domestic violence should seek help by calling 211 and connecting with crisis counselors.

"One's too many," he said. "We need to focus more on prevention and education."

This story has been updated to reflect that Michael Edward Kurz died of "upper body trauma," according to the Sheriff's Office. The agency has not specified the type of trauma. An earlier version of this story incorrectly presumed that both men died the same way.
