Family members discovered Redelma Belisario's body at a home on Tuesday afternoon.
The Integrated Homicide Investigation Team says it's asking for the public's help in locating her 38-year-old son, Darwin Lescano.
Sgt. Stephanie Ashton of IHIT says an autopsy will be done to confirm the cause of death but investigators believe foul play was involved.
She says anyone who sees Lescano should call police immediately and not approach him.
Lescano is described as five-foot, six-inches tall, dark skin, 140 pounds, and may have a shaved head or close cropped hair.
