GREENWICH TOWNSHIP, N.J. (CBS) -- A South Jersey man who led authorities on a nationwide manhunt has confessed to 16 murders, prosecutors say. Sean Lannon, of Greenwich Township, is a suspect in the murder of 60-year-old Michael Dabkowski in New Jersey and is suspected in four murders in New Mexico.

One of the victims is his ex-wife.

Lannon told the court 11 of the other victims are drug dealers.

A judge ruled Lannon is a flight risk. He remains in a Salem County jail cell.
