PHILADELPHIA -- Police in Philadelphia say a 20-year-old woman posted an open offer of $1,000 to kill the father of her child and a man responded that he'd do the killing.

Investigators say London Eley posted a message last month on Facebook saying, "I will pay somebody a stack to kill my baby father."

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.
