Arlington police say a 66-year-old man shot and killed his neighbor outside his home on Tuesday.
Franklin Hudson was arrested Tuesday on suspicion of murder in connection with the shooting death of 36-year-old Arlington Haney on Redbrook Court.
“It is right now a dispute that existed between these two men,” police spokeswoman Cheryel Carpenter said.
Neighbors said Haney rode his bike from his property three houses over toward Hudson's home, where the two men began arguing about Haney's dog. Witnesses said Hudson began shooting, firing at Haney and at people who ran to help him at about 7 p.m.
"They did attempt to assist him," police spokesman Sgt. Christopher Cook said. "Unfortunately, as they were trying to help out, they were shot upon. None of them were hit and were able to take cover."
Authorities are investigating a possible feud between the men.
Neighbors said they would not describe the situation between Haney and Hudson as a long-standing feud but said the two men had a history of incidents, including arguments about dogs on one another's properties and anger over associating with and talking to others based on race. They also said weapons were brandished at times.
But neighbors said they never thought the disputes would lead to a fatal shooting.
“I've seen [Hudson] be grumpy before, but I just thought he was the grumpy old guy -- nothing like that though,” Zachary Jenkins said.
Police said Hudson did not put up a fight as he was taken into custody. He is in the Arlington Jail facing murder charges. Bond has been set at $500,000.
Haney's death is Arlington’s seventh homicide this year.
