Authorities: N.J. man murdered ex-girlfriend's grandmother, brother after argument

Authorities in New Jersey have identified a man who they say killed his ex-girlfriend’s grandmother and younger brother earlier this week.

Terrence J. Matthews, 23, has been charged with two counts of first-degree murder, one count of kidnapping, and other related charges.

Officers were called to a Wawa on Springside Road in Westampton Township for a report of a woman in distress, who told a store employee that her family had been murdered by her ex-boyfriend. The 22-year-old woman fled before officers arrived.

Police then responded to a home on the 100 block of Eastbrook Lane to conduct a wellness check. Once inside the home, they found the bodies of Jennifer Vassell, 68, and her 9-year-old grandson Ishon Mathiln Jr.
