Resident John Waterman, who lives on Mystic Avenue said Wilmington police came to his house earlier this morning looking for the alleged suspect. Waterman is a long-time friend of the suspect, who only recently ran into him a month ago. 

Waterman says the man in question has talked about suicide before and the suspect's parents, an uncle and a brother live in the Oakdale Road house. Waterman says he's worried about the family and worried the suspect will shoot at police.

The suspect, said to be a former member of the Air Force, is said to be known to police, who have been called out to the house five to six times in the past few years. Unconfirmed reports say guns and ammunition have been removed from the home in the past.

Chuck Shay, a resident of 21 Oakdale, lives across from the house from the scene. He was out walking his Golden Retriever this morning when he heard gun shots.

"I take my dog for a walk every day around the same time, around 7:30. I heard some yelling and then heard two or three gunshots, really loud shots," Shay says. "I turned around to go back to my house and heard all these sirens. I got back to Oakdale and was told I couldn't go back. I was told the neighborhood had to evacuate for SWAT. I've been here for 15 years. It's a tremendous neighborhood. You can leave your doors open."
