New Jersey authorities announced earlier this week that a tip from a Facebook user led them to arrest a man for the November 2010 murder of a 55-year-old Union Township woman.
He's being charged with homicide and is being held in jail in lieu of a $1 million bail.
Police said their 17-month investigation of the stabbing death of the woman had failed to turn up a suspect in the case.
But a Massachusetts woman recently gave law enforcement officials a tip about a man she said she'd been in contact with on Facebook.
According to police, the Massachusetts woman's tip led them to a 26-year-old New Jersey man, described as a drifter.
The man's mother lived across the street from the murdered woman's house.
The Massachusetts woman said she'd been in contact with the suspect on Facebook when she learned about the murder case. She then reportedly elicited information about the case from him, which she then turned over to police.
The suspect was arrested this past weekend about 25 miles south of Englewood.
Law enforcement authorities claim the man left behind at the murder scene forensic evidence linking him to the crime.
According to a report by CBS New York, the murdered woman had apparently been having work done at her home at the time of the killing, but police didn't say if the suspect was linked to that renovation project.
Police say they don't know of a motive for the killing.
