Mesa police say the mother's boyfriend has been arrested in the death of a 14-year-old girl whose body was found in a dumpster last week.
Mesa Police Chief Frank Milstead said 31-year-old Alex Anthony Madrid is facing charges of first degree murder, kidnapping, sex conduct with a minor, molestation of a child, child abuse, sexual abuse, abandonment/concealment of a body and tampering with physical evidence.
Officers got a call for a body found in a dumpster around 12:30 a.m. Friday at the Sun Garden Apartments near Brown Road and Stapley Drive.
On Monday, the victim was identified as 14-year-old Claudia Ann Lucero, a student at Westwood High School.
She was reportedly last seen at her Mesa home around 6:30 a.m. Thursday.
Milstead said Madrid was the boyfriend of the victim's mother who used to live with them.
He recently became estranged from the family, according to Milstead.
Police said in a Tuesday afternoon news conference that the cause of death was strangulation.
