HOUSTON -- Police believe the man accused of shooting a neighbor in northeast Houston early Tuesday is the same man who fatally shot two other people in northeast Harris County on Monday, including his ex-wife.

The suspect has been identified as Russell Cormier, 53, according to the Harris County Sheriff's Office.

Around 4 a.m. Tuesday officers responded to an area near the suspect's home on Shotwell south of Bennington. A resident said his neighbor shot him in the stomach and then fled the scene.

The victim was taken to the hospital as the manhunt for the shooter got underway. The victim is expected to survive.

Police recovered a pistol and a shotgun in the victim's front yard, but it's believed Cormier is still on the run with another shotgun, police said. He may be in an early 2000s Dodge Stratus sedan.

Houston Police set up a search perimeter with a K-9 unit, but so far no arrests have been made.

Police and firefighters were in the same neighborhood yesterday after a fire was reported on the suspect's property.

The fire occurred after deputies said a 61-year-old woman was fatally shot at her home in the 12300 block of Green Canyon Drive. She has been identified at Fannie McWhite, Cormier's ex-wife. Less than two hours later, a man was shot outside his work in the 12200 block of Kindred.

Harris County Sheriff's Deputies and Houston Police are now working on the cases together as it's believed the same man is responsible for all three shootings.

Sheriff Ed Gonzalez says he's hoping digital billboards going up will help catch Cormier.
