DETROIT – The father of a missing Detroit girl who claimed his daughter was stolen in a carjacking has failed a polygraph test, MyFoxDetroit.com reports.
Police are still questioning 32-year-old D'Andre Lane, the father of 2-year-old Bianca Jones.
Lane claims a man with a gun carjacked him Friday morning and drove off with Bianca buckled into her car seat.
Lane's car was recovered 10 minutes later, but Bianca was missing.
Detroit Police Chief Ralph Godbee says the reward for information leading to Bianca's return is now at $17,500 thanks to a businessman's donation. Godbee asked witnesses to come forward with what they know during a news conference Saturday.
"If you've seen her picture, seen that smile, if that does not move your heart to do the right thing -- as my grandmother would say, there's no 'do right' in you," Godbee said.
Banika Jones begged whoever has her daughter to drop the child off somewhere safe.
Officers have searched vacant homes in the area.
Police say two people were involved in the carjacking. They released a sketch of one.
