An Atlanta man was arrested Monday and charged in the deaths of two cousins who were killed execution-style last year in DeKalb County.

Russell Rijon McNeal, 26, faces two counts of murder, almost exactly two months after the bodies of Michael Wigfall and Robert Sean Collier were found at a home on Old Lake Drive, according to a statement from the DeKalb County Sheriff’s Office.

Wigfall, 33, and Collier, 36, left behind a total of six young children.

Arrest warrants for McNeal were obtained Thursday, and he was arrested Monday at an apartment complex off Panola Road near Lithonia, the sheriff’s office said.

Officials did not provide a motive for the shootings or say what led them to arrest McNeal.

The victims were lying on the floor in the home when police arrived about 1 a.m. on Dec. 10, according to an incident report obtained by AJC.com. They each had gunshot wounds to the head, police said.

“This has broken us totally apart,” Rebecca Mahoney, Collier’s sister, told Channel 2 Action News in December. “They senselessly just took his life.”

The family was told by police that the men were killed execution-style, Mahoney told the news station.

Channel 2's Tyisha Fernandes learned the two victims were close cousins who were always around each other.

According to the police report, one of the men was found lying by the front door while the other was near a sliding glass door. The front door appeared to have been forced open, police said.

A neighbor told police he noticed the door was open when he got home. He saw two people show up in a red SUV; one person went into the house and “quickly came out” before driving away, according to the report.

He then saw “a foot hanging in the doorway” and called police.

Another neighbor said she heard gunshots.
