Cops: Man fatally shot pair who tried to rob him—but as they ran away. Now he's charged with murder.

The perps figured Jarrell Chaney had marijuana, so they targeted the 31-year-old for a robbery on Tuesday, police in Irving, Texas, told KTVT-TV.

But Chaney got the upper hand against the trio, wrestling a gun from a juvenile suspect — and then he began shooting at them as they ran away, police told the station.

Two of them — 18-year-old Ishmeal Smithson and 19-year-old Theophilos Greer — later died, KTVT said.

And now Chaney is in jail on murder charges, the station said.

'I don’t think it’s that fair'

“I was like, it couldn’t be murder. Not here, not in this apartment," LaShandra Holt — a resident at the Irving apartment complex where the shooting occurred — told KTVT. "It was just really shocking."

But Holt doesn't necessarily agree with how Chaney's been treated.

“You’re going to do whatever you can to save your life," she told the station. "I don’t think it’s that fair."

'There's no longer that threat'

Pete Schulte, an attorney and former police officer, told KTVT he's not surprised by the murder charges.

“If a robbery had taken place, or attempted robbery, and the victim had a gun and shot them during the commission, that would be self-defense,” Schulte told the station.

He added to KTVT that "the individuals who pulled the gun on the victim were disarmed and were running away, there's no longer that threat. So the police have to look at the totality of all the circumstances and make a decision.”

To determine if the shootings were justified, police told the station they're also looking at how far away the fatally shot men were from Chaney when he pulled the trigger. Police told KTVT they believe the shootings weren't justified, but that the investigation is still in its early stages and that the final decision will come from the district attorney.

The third suspect — the juvenile — wasn't injured and isn't facing any charges, the station said.
