It happened shortly before 6 a.m. Tuesday on James Avenue and Estates Drive.
New Jersey State Police were called to the scene.
Action News spoke with the father of the man who allegedly pulled the trigger. He described the incident as an attempted murder-suicide.
He said his son shot a woman and then turned the gun on himself.
"It all stemmed from them fighting and my daughter-in-law kicking him out," said Rick Ellis Sr.
He said his estranged son, Rick Ellis Jr., 42, shot a woman in the home of his ex-girlfriend and then shot himself.
"I guess he was having a hard time. He was homeless and he came back apparently for revenge," said Ellis.
Video from Chopper 6 showed at least one victim being loaded into a helicopter.
Ellis said his son has struggled with substance abuse since the death of his mother several years ago.
He said the woman his son shot was not his ex-girlfriend, but rather a young woman who also stayed there in the home.
He also said two days ago his son called a suicide hotline and New Jersey State Police tried to check on him, but he didn't know where his son was staying.
"Sad situation. I didn't think it would come to this. I kind of felt that he wanted to do something to himself especially after that suicide hotline thing. I didn't know it would get this far. That he would take it out on them. And where the gun came from I don't know. I didn't even know he had guns," said Ellis.
Ellis said his son had surgery Tuesday but has suffered considerable brain damage.
Police have not released a condition for the woman who was shot.
