NEW YORK (AP) — Authorities say a 48-year-old man dragged his pregnant girlfriend into the stairwell of her Queens apartment building and stabbed her to death.

Anthony Hobson was arraigned Friday on charges including second-degree murder in the death of 35-year-old Jennifer Irigoyen.

Prosecutors say surveillance video shows Hobson dragging Irigoyen into the stairwell of her building early Sunday and stabbing her multiple times.

Irigoyen, who was 14 weeks pregnant, was pronounced dead at a hospital.

Queens District Attorney Richard A. Brown says Hobson showed "no mercy and no regard for human life."

An attorney for Hobson did not return a call seeking comment.

Hobson faces up to 25 years to life in prison if convicted.
