PROVO — Police are still investigating a woman's death after she was found unconscious and not breathing in a bathtub Tuesday afternoon.

The woman, in her 40s, was found in the bathtub by a family friend who came over to pick the woman up for a planned outing, said Provo Police Capt. Cliff Argyle.

When the woman didn't come to the door, the friend went inside the home near 100 S. 700 West in Provo, then called police around 1:30 p.m.

"The paramedics were called out to a female, unconscious in a tub," Argyle said. "I believe they put it out as a drowning, but we can't say that for sure."

Paramedics performed CPR on the woman as they rushed her to Utah Valley Regional Medical Center, where she was declared dead, Argyle said.

"They left the home lights and siren, so they had reason to believe she was still alive until they got to the hospital," Argyle said. "They were working on her, trying to sustain life until the hospital, and a doctor (could) decide otherwise."

Because of the death, detectives were called out to the scene, but Argyle said after a preliminary examination of the woman and the situation they don't suspect foul play.

The woman had recently had foot surgery, though Argyle wasn't sure if that played any part in her death.

The State Medical Examiner's Office will be responsible for determining the exact cause of death.

The woman's name has not been released yet, pending notification of family.
