A woman suffocated her 12-month-old son, then died of an apparently self-inflicted gunshot wound in Shrewsbury Township Monday, state police said.

Police said they responded about 1 p.m. to the 12000 block of Baltimore Street in the York County township to check on the welfare of a 40-year-old woman. The woman was found lying in bed, dead of the gunshot wound to the head.

Her son, police said, was intentionally suffocated by the woman.

No further details were available Monday night.

Autopsies are pending, and the investigation continues, police said.
