A 16-year-old boy has been charged as an adult in the shooting death of a 15-year-old boy in Allentown on Sunday, according to Lehigh County officials.

Lehigh County District Attorney Jim Martin and Allentown Police Chief Charles Roca announced Tuesday that Elijah Patterson, 16, is charged as an adult with criminal homicide, a first-degree felony, in Sunday’s shooting at Stevens’ Park in the city.

Martin and Roca said Patterson shot Treshawn J. Tracy, 15, after an altercation between Patterson and Tracy under a pavilion in the northeast corner of the park.

Patterson is also charged with possession of a firearm by a minor.

He was denied bail Tuesday morning and is in the Lehigh County Jail.
