An 81-year-old woman died April 14 after being beaten up by suspected robbers, and those teens have been arrested.

Sheriff deputies said Dorothy Pauline Session was found around 6:30 p.m. on April 14 in her living room by her grandson.

Deputies said he went to check up on her after Session had missed an appointment earlier in the day.

Deputies said they don't know how long Session had been laying injured in her home.

They said Session had severe injuries on her nose, cheek bone and on the side of her face.

Authorities believe the suspects entered Session’s home through an unlocked back door and assaulted Session. It does not appear that any items were stolen.

During the investigation, detectives received information that before the assault, two Hispanic or black females and one black male were walking through the neighborhood.

According to witnesses, these people were knocking on doors, checking to see if anyone was home.

The Kern County Sheriff's Department arrested 17-year-old Angelique Elandra Nash and her sister, 15-year-old Katila Ann Jean Nash, Saturday afternoon near the Extended Stay Hotel at 3600 Chester Lane after homicide detectives were contacted about the girls' whereabouts.
