According to the criminal complaint, Stiles was giving Hyska, who was in the group home because of spastic quadriplegia and blindness, a bath on the night of Aug. 28 when she left the bathroom to answer the phone.

When she returned, Hyska was underwater. Stiles told authorities she pulled Hyska from the bathtub and called 911 while administering CPR.

When an officer from the Braham Police Department arrived, he saw Stiles giving Hyska chest compressions on his back. The officer flipped him over and took over CPR until paramedics arrived. They transported Hyska to Cambridge Medical Center where he was pronounced dead.

According to court papers, Stiles told police that she was only on the phone for one to two minutes before returning to the bathroom to find Hyska underwater. But according to phone records, Stiles was on the phone for more than six minutes.

If convicted, Stiles faces up to 10 years in prison and a $20,000 fine.
