Man fatally shot after argument over dog in Garland, police say

Garland police are investigating a deadly shooting Saturday night that investigators said happened after an argument between neighbors over a dog.

Police said 18-year-old Isaiah Kellough has been charged with murder.

The shooting happened just after 7:30 p.m., when police believe a fight started between neighbors about a dog in the 1600 block of Running River Road.

"From what we know, [the argument] appears to be over a dog," Garland PD PIO Matt Pesta said.

The fight then escalated to a shooting.

When officers arrived on scene, they found 33-year-old Rontarious Hamilton with a gunshot wound.

He was taken to a hospital and later died.

After talking with family members and witnesses, police arrested Kellough for the shooting. 

Police said Kellough wasn’t involved in the initial dispute.

Hamilton was arguing with one of Kellough’s family members.

Investigators said it’s still unclear how Kellough got involved.

"Once you take that path, you can’t backtrack. That’s exactly what happened here. It’s sad, all the way around, for everybody involved," Pesta said.

Police are working to find out why Kellough made the decision to fire the gun.

"Permanent outcome to a temporary situation and you've got multiple families involved here that are in pain. You obviously have the deceased, and then you have the shooter’s family," Pesta said.

Hamilton’s family said he leaves behind two children.
