A 60-year-old North Little Rock man who was shot overnight in his home died of his injuries Thursday while being treated at a hospital, authorities said.

Officers responded around 9:20 p.m. Wednesday to the 4200 block of Coral Street where they found the man – later identified as Ernest McCoy – suffering from an apparent gunshot wound to the head, according to the North Little Rock Police Department.

Medical crews brought McCoy to UAMS Medical Center for life-threatening injuries before he died shortly after noon, police said.

Officials said officers interviewed and later arrested 69-year-old Charles C. Leavy, who’s suspected of firing a gun inside the home.

He appeared in North Little Rock District Court Thursday morning on first-degree battery charges, but because of the McCoy’s death, police plan to charge Leavy with second-degree murder.

Police said Leavy and McCoy lived at the same home, but it wasn’t immediately known what led to the shooting.

Leavy remained at the Pulaski County jail Thursday with bond set at $100,000.

Records didn't list an attorney representing Leavy to comment on the charges.

The shooting came before a separate killing Thursday morning in North Little Rock, tripling the city’s homicide count in less than 24 hours and bringing the total to three so far this year.

Police confirmed Thursday afternoon that a gunman shot a person in the 600 block of W. 18th Street.

The investigation into both killings is ongoing, officials said.
