Murder-suicide investigation underway in Bradenton

Manatee County detectives have launched an investigation after two people were found dead inside their Bradenton home. 

Investigators say Jeff and Jennifer Long were found dead in their bedroom following an argument between the couple. Detectives believe Jeff shot his wife, then proceeded to shoot himself. A juvenile daughter and a family friend were at the home at the time of the shooting. 

Many neighbors who spoke with FOX 13 say they were in shock when they heard the news.

"It just made you sick to your stomach because you are wondering what happened," one neighbor said. 

It's disturbing because I've known Jeff for a while," another neighbor said. "He's been to our house numerous times."

The Manatee County Sheriff's Office said the couple had recently been experiencing marital problems. 

No other details have been released.
