COTTONWOOD HEIGHTS — A Cottonwood Heights woman has been charged with negligent homicide, a class A misdemeanor, after her 7-month-old daughter drowned while left unattended in a bucket of water on July 19.

Kelsey Singletary, 22, told police she was bathing her daughter, Seyena, in the bucket in the bathroom when she stepped away to call her cousin on the landline phone. She told police she didn't have good reception on her cell phone. The bucket had about 7 inches of water in it, according to charges filed Sept. 9 in 3rd District Court.

Singletary said "she had been away from the bathroom on the phone for four to five minutes" and "could have been away from Seyena for as long as eight minutes," the charges state.

However, Singletary's cousin turned her own cell phone over to police following the incident. It showed the phone call between Singletary and her cousin lasted 16 minutes 29 seconds, according to the charges.

Police said that when Singletary returned to the bathroom, she found her daughter's face under the water. She removed Seyena from the bucket and told police she began CPR. She told investigators: "I shouldn't have been on the phone. That's a long time to leave a baby alone in the bathtub," the charges state.

Seyena was kept alive on life support, but prosecutors say she never regained neurological function. She was taken off life support and died July 24.

Following an autopsy on the infant, a medical examiner ruled Seyena's death an accident.
