SOMERSWORTH, N.H. — A 52-year-old New Hampshire man has been arrested in the beating death of a 79-year-old man in the parking lot of a Walmart in southeastern New Hampshire, authorities said Saturday.

Somersworth police said they arrested a local man, Brian Roberge, after responding to a call about the late Friday killing. At the scene, they found Jan VanTassel, of Center Ossipee, unresponsive with head and facial injuries. First responders determined he was dead.

Police said they think Roberge killed VanTassel by striking him repeatedly in the head and face.

Roberge is charged with second-degree murder. He is due in court Monday.

It wasn’t immediately clear Saturday if Roberge had an attorney yet.
