EL CAJON (CNS) - A man who admitted neglecting his severely disabled older brother, resulting in his death amid squalid conditions, is scheduled to be sentenced in El Cajon Friday, along with his mother.

Deborah Dawn Marlow, 59, and Christopher Travis Marlow, 27, both of El Cajon, each faces up to seven years in prison. They pleaded guilty in May to dependant adult abuse causing great bodily injury in the death of 28-year-old Jeremy Marlow.

According to prosecutor Kurt Mechals, Deborah Marlow was the victim's primary caregiver in earlier years, and Christopher Marlow took over that role in recent years.

On Jan. 26, 2010, Jeremy Marlow, who was severely developmentally disabled and suffered from cerebral palsy, died after five days at Grossmont Hospital. The hospital staff described the patient's condition as the result of "torture," Mechals said.

According to the San Diego County Sheriff's Department, Jeremy had not seen a doctor in a year, weighed less than 100 pounds and was covered with sores when he arrived at the hospital. Doctors said he was brought in too late to be saved.

Investigators who went to the Marlow family's apartment on Graves Avenue in unincorporated El Cajon found the door to Jeremy's room locked and had to pry it open, according to Mechals. When they did, they found a mattress covered in body waste and black mold.
