West Palm Beach, FL - A South Florida man has been convicted of shooting a neighbor because of a laundry room door that had been left open.

A Palm Beach County jury found 39-year-old Jack Abrams guilty Tuesday of aggravated assault with a firearm. He faces a minimum of 25 years in prison at his Nov. 5 sentencing.

Authorities say Abrams shot 52-year-old Timothy Gwinnell in 2010 following an argument with Gwinnell's girlfriend.

The Palm Beach Post reports that the woman had left open a laundry room door in their apartment complex, and Abrams became angry and complained to the woman.

When Gwinnell went to investigate the commotion, Abrams pulled a gun he carried and shot Gwinnell several times.

Abrams has never denied being the shooter. The former U.S. Marine's attorney argued that Abrams suffered from post-traumatic stress syndrome and snapped.
