- Police believe the photo might have been taken up to an hour prior to the girl's death
- Evidence shows contact with a frayed extension cord likely led to electrocution
CNN (CNN)As she often did, 14-year-old Madison Coe ran a bath to unwind before bed.
She took her phone into the bathroom and was careful to keep it dry as it charged, laying its power cords on a towel. Madison snapped a photo of her setup and sent it to a friend with the message, "When you use (an) extension cord so you can plug your phone in while you're in the bath."
It was the last time anyone heard from her.
A police investigation concluded that Madison was electrocuted July 9 while in the bathtub at her father's home in Lovington, New Mexico. Lovington Police spokesman David Miranda said the photo might have been taken up to an hour before she died.
Now her family has released that last text message she sent in the hope of preventing similar accidents.
"She had her phone plugged into the extension cord and it was by the bathtub, and I did it, she did it, we all had sat there in the bathtub with our phones plugged in and played our games," Felisha Owens, Coe's stepmother, told CNN affiliate KRQE.
How it happened
The girl's phone was plugged into a charger, which was plugged into an extension cord connected to a "non-GFCI, non-grounded" bathroom wall outlet, police said. Miranda said police believe that by the time of the incident, the phone adapter cord had been disconnected from the extension cord.
