BULLHEAD CITY (AP) - An 8-year-old girl reported missing from her Bullhead City home was strangled to death, authorities said Friday as they continued to investigate the case.
The Mohave County medical examiner released the manner of death for Isabella "Bella" Grogan-Cannella on Friday. The cause of death was asphyxiation.
Police found Isabella's body in a shallow grave near her Bullhead City home Wednesday, a day after her family reported her missing.
Isabella was discovered wearing the same green, ruffled, sparkly tank top she had on when she was last seen. However, authorities said she didn't have any clothing on her lower half and they are looking into whether she was the victim of sexual assault.
Justin Rector, a 26-year-old Bullhead City man with a lengthy criminal history, was charged with kidnapping and first-degree murder in her death. Authorities described him as a family friend who was staying at Isabella's home at the time she disappeared. He is being held without bond.
Meanwhile, teachers and administrators at the schools Isabella attended remembered her as friendly, loving, obedient, beautiful and inquisitive.
Diamondback Elementary School Principal Martin Muecke told the Mohave Daily News that Isabella paid close attention to detail when crafting sentences. Her second-grade teacher, Kaycee Larson, said Isabella's favorite subjects were English, language arts and writing.
Desert Valley Elementary School Principal Cynthia Cochran said it's unfortunate others won't get to know Isabella.
"I think anyone who has children or who works with children is devastated by this tragedy," Cochran said.
Police said they aren't ruling out additional charges or arrests in their investigation into Isabella's disappearance and death.
According to court records, Isabella's mother was not home at the time her daughter went missing. She and others went to Walmart, and she told Isabella and her 10-year-old sister to lie down in bed and watch a movie. The mother of her boyfriend was home with the children, court records state.
Bullhead City Police Chief Brian Williamson said Thursday that the state Department of Child Safety is involved but did not elaborate.
