'Cops on me': Suspect goes on Facebook before being arrested in death of 4-year-old, grandmother

WILLINGBORO, N.J. -- A New Jersey man live streamed his attempted getaway on Facebook after killing a 4-year-old and a grandmother, according to sources.

The Burlington County Prosecutor's Office confirmed two people were found dead inside a home in Willingboro, New Jersey, on Thursday. Sources said those two people were a grandmother and her 4-year-old grandson.

Investigators believe they were stabbed to death after a domestic dispute between the boy's mother and her ex-boyfriend.

Video obtained by WPVI shows the suspect on Facebook with police sirens ringing in the background.

"Cops on me," the man said in an obscenity-laced diatribe.

The sound of screeching tires could also be heard as he speeds through the streets of Camden.

"Seatbelt off, I love y'all," he says moments before crashing into a utility pole and being taken into police custody.

Authorities have not yet identified the suspect or the victims.

Sources said the suspect will be charged in the double murder.
