LITTLE ROCK, Ark. — One of two teenagers charged in the death of an Arkansas police officer has pleaded not guilty to capital murder and several other charges.

KATV-TV reports that a 16-year-old entered the plea Thursday in the June 12 fatal shooting of Newport Lt. Patrick Weatherford. An 18-year-old pleaded not guilty to furnishing a deadly weapon to a minor, breaking and entering and property theft.

The 18-year-old posted bond last month.

The 16-year-old’s attorney requested a mental evaluation for his client, who is being held at a juvenile detention center.

Prosecutors say Weatherford was shot while investigating a vehicle break-in in Newport, about 90 miles (145 kilometers) northeast of Little Rock. He died at a hospital that night.
