Man shot two Arkansas siblings, killing one. But, officials still don't know why.

An Arkansas man shot two brothers, killing one. Now, he will remain behind bars for the rest of his life.

Recently, Crittenden County Circuit Court Judge Randy Philhours sentenced Sir Jeffery McNeil-Lewis to three life sentences in prison for the double shooting, and murder of Jarvis Moore, 34. McNeil-Lewis, who was initially released on bail, was found guilty and convicted after a three-week trial of first-degree murder, attempted first-degree battery and eight counts of terroristic acts.

On Jan. 22, 2021, the West Memphis Police Department in Arkansas responded to a report of shots fired in a residential neighborhood at McCauley and Twist Drive. When officers arrived, they found Moore with a gunshot wound to the back of the head.

Eyewitnesses and neighbors heard several gunshots and told officers of another victim that drove away from the scene to a nearby gas station on Ingram Boulevard for help. There, officers found Moore’s brother with a fresh gunshot wound to the arm.

Moore later died of his injuries, while his brother survived the ordeal.

Later, authorities arrested 28-year-old Moore and Montrell Dellshun Williams for the double shooting. Investigators found a gun within the premises where the defendant was arrested. A ballistic test was carried out on the gun, and it was determined to be the murder weapon used to kill Moore. In addition, gunshot residue was found on McNeil-Lewis’ hand.

“This was a senseless murder in a residential neighborhood and broad daylight. And the jury’s message is crystal clear — Crittenden County citizens demand safe neighborhoods and will not tolerate gun violence,” said Prosecuting Attorney Keith Chrestman, according to FOX 13.

The motive for the homicide remains unclear.

Neighbors were alarmed such violence was carried out in their neighborhood in broad daylight. A school bus was seen dropping off children just after the police removed the crime scene tape, reported WREG.

Philhours ordered McNeil-Lewis to serve an additional 290 years in prison to the life sentences. Williams is scheduled for trial on April 4.
