The two teens are facing three counts of murder in addition to weapons charges. Baskerville also is charged with aggravated sexual assault.
The two youths along with four other suspects are charged in the execution-style slayings of three friends with promising futures.
Twenty-year-old Iofemi Hightower, 20-year-old Dashon Harvey and 18-year-old Terrance Aeriel were shot as they knelt in front of a wall in a school playground.
Aeriel's sister, Natasha, who survived the shooting, helped authorities identify suspects.
Baskerville and Gomez are each being held on $1 million bail.
