CLEVELAND, Ohio -- An 15-year-old boy was arrested Wednesday in connection with the death of a 16-year-old boy found shot dead in an abandoned building in the city's Slavic Village, police said.

Cleveland Police Sgt. Jennifer Ciaccia confirmed the arrest on Thursday. No information about the arrest was immediately available.

Alex Mullins was found shot to death Nov. 20 in a building in the 3700 block of 54th Street.

Mullins was last seen by family members on Nov. 9 after his father dropped him off at Washington Park Environmental Studies, a technical school that teaches landscape design and animal and plant science management.

His father, Henry Mullins, reported him missing after he never showed up at his mother's apartment in Parma.

The family began a daily search through vacant homes in the neighborhood. They scoured dumpsters and vacant fields looking for him or his cellphone that last pinged near East 50th Street and Chard Avenue.

Cleveland police asked for the public's help in finding Mullins four days after he went missing.

A woman called police Nov. 20 and said that her son heard rumors that Alexander Mullins was dead inside the building in the 3700 block of East 54th Street, police reports say.

Officers went to through the backdoor of the boarded-up building that sits between two vacant lots. They found him dead with a gunshot wounds to his left chest, according to police.

Police found bullet casings on the ground and a puddle of blood near Mullins, according to police reports.

Henry Mullins previously said his son had typical teenage problems and was expelled from Parma schools for skipping classes and smoking cigarettes with friends. He enrolled his son at the Washington Park because he thought it would be safer.
