Authorities say 18-year-old Timothy Bynum, of nearby Darby, offered to do the killing and Eley provided an address and description of her ex-boyfriend, who contacted police.
Officers who searched Bynum's home say they found a .22-caliber handgun.
Eley is charged with solicitation to commit murder and Bynum is charged with attempted murder and conspiracy. Neither has posted bail.
Bynum's mother tells KYW-TV her son is innocent and she's hiring him a lawyer.
