A Utah Highway Patrol dive team returned to Lake Powell on Monday hoping to locate and recover the body of a physically disabled South Jordan woman believed to have drowned in a boating accident last week.

Jessica Jackman, 22, and 29-year-old Valerie Bradshaw went missing Thursday after a motorboat they were riding in collided with a houseboat. Jackman's mother, 57-year-old Marilyn Jackman, died at the scene of the crash.

Bradshaw's body was located at 7:12 p.m. Sunday. A remote-controlled robotic submersible then recovered the remains from 340 feet below the surface. The body was transported to nearby Wahweep Marina, where it was turned over to the Kane County medical examiner.

Divers on Monday explored the same area of the lake where Bradshaw's body was found, said Kane County sheriff's Sgt. Alan Alldredge.

Jessica Jackman had Stickler syndrome, a genetic disease characterized by physical abnormality, hearing loss, and eye and joint disorders. She had recently graduated from Salt Lake City's Westminster College with a degree in social work.

Alldredge earlier reported that the motor boat's driver — Jackman's father, Adrian — may have been distracted by children onboard as he neared the houseboat, which was anchored near the Dangling Rope Marina on Thursday morning.

Adrian Jackman attempted to veer away from the houseboat, but still struck its front.

The accident remained under investigation Monday.
