Addressing reporters at a late-afternoon news conference, Bloom said the boyfriend, Marquise Ellison, 24, of the 5300 block of Thomas Avenue in Kingsessing, was arrested on a warrant charging him with murder.
Police said Ellison was arrested after Courtney's mother, Shatara Fletcher, 26, gave a statement implicating him in the killing.
Investigators at first suspected that Courtney might have died from ingesting hot pepper seeds and possibly hot sauce over the weekend in her mother's apartment in the 800 block of South 55th Street in West Philadelphia. Although peppers were found in the child's stomach at autopsy, any possibility of accidental death was ruled out after the autopsy.
Investigators said Ellison apparently became enraged and attacked early Sunday when he found the toddler and her 1-year-old brother, Corey, getting things out of the kitchen cabinet. Investigators said it appeared that only the older child had been punched and beaten.
Paramedics answering a 4:45 a.m. call for help from a neighbor's apartment found Courtney unresponsive and rushed her to Children's Hospital of Philadelphia, where she was pronounced dead about 35 minutes later.
Fletcher, who was picked up Monday evening and taken to Police Headquarters for questioning, was not arrested. "At this time, we are not charging the mother," Bloom said.
Yesterday afternoon, Ellison walked into Police Headquarters at 12:35 accompanied by Homicide Detectives Thomas Augustine and Greg Rodden. He did not respond when asked by a reporter if he had killed the little girl. He was being held last night at Police Headquarters pending arraignment on the charges.
