A 10-year-old boy was being held in the fatal beating of an 18-month-old girl he apparently was baby-sitting, police said.
"He is the suspect," police official Chris Olson said Sunday. "We have no other suspects."Olson said little Jazmine Haen appeared to have been beaten to death with a blunt instrument, but would not elaborate.
Police were called Saturday evening to the boy's house in a working-class section of this Denver suburb. When officers arrived, they found Jazmine with "significant traumatic injuries on her entire body," Olson said. The girl died early Sunday at a hospital.
Olson said a 19-year-old man, believed to be the 10-year-old's brother, was sleeping in the house while the younger boy apparently was baby-sitting the little girl.
The girl's parents were not in the home at the time, Olson said.
The girl's mother, Roberta Corder, 18, said she had noticed bruises on Jazmine after the older brother had been around her in the past.
"I don't know why I got to where I trusted him," she said. "She used to scream when she'd see him."
Police did not explain the relationship between Corder and the brothers, or why the 19-year-old was not a suspect.
The boy was being held at a juvenile detention center pending the completion of the investigation.
