ST. PETERSBURG, Fla. (TBO.com) - A St.Petersburg man, who may suffer from post-traumatic stress disorder, is charged with killing one man and wounding two others Saturday because he believed they were dealing drugs in his neighborhood, police said.

Police received reports of a shooting in the 4300 block of 7th Avenue North about 10:04 p.m. Officers found two wounded men in the street. One of them was Alexander Usher, 32, of 4324 7th Ave. N., and the other was Mackenzie Galen McConnell, 26, whose last known address was 1701 Woodmarker Court in Brandon.

A third victim, David Oard, was wounded while inside his home.

All three men were taken to a hospital. McConnell was wounded in the upper body and was pronounced dead at 12:27 a.m. Sunday at BayfrontMedicalCenter. Oard was treated for a minor wound after a bullet grazed his head and Usher, who suffered a gunshot wound to the lower body, was being treated, police said.

Usher and McConnell were in a parked vehicle in the 4300 block of 7th Avenue North Jason Faber approached them, pulled out a semi-automatic handgun and fired several times, according to police.

Stray rounds apparently entered Oard’s home at 4321 7th Ave. N. and wounded him, police said.

Then Faber, 34, of 4314 7th Ave. N., got into his 2004 silver Mazda RX-8 and fled with the handgun, police said.

Faber’s wife told police her husband served in the military, suffers from post traumatic stress disorder and apparently believed residents of Usher’s house, 4324 7th Ave. N., were dealing drugs. She did not know why her husband shot them and there did not appear to be any provocation, police said.
