Baltimore County police continued on Tuesday to investigate the suspicious deaths of a mother and her 4-year-old daughter whose bodies were found in their Parkville apartment.

Authorities identified the victims as Alicia Avery, 25, and her daughter Darry'el Parker. They were found by police officers Monday afternoon in a bedroom of their temporary residence in the 8700 block of Loch Bend Drive.

A cause of death had not been announced by Tuesday evening, and no arrests had been made. But county police spokeswoman Cathy Batton said the victim had been relocated to the apartment by city police. She said county police were unaware that Avery and her daughter were at the apartment.

Avery was a witness in an investigation of a March murder in Baltimore City and had been cooperating with police, said city law enforcement sources who cannot be identified because they are not authorized to speak publicly about the case. City police officers found the bodies, one source said, after they were unable to contact Avery.

The pair had not been seen for several days, investigators said.

Avery's cooperation with police is only one element of the county's investigation into her death, Batton said. She declined to comment on a possible motive in the slaying.

Neighbors said that Avery may have been pregnant, according to a WJZ report. Police are waiting for pregnancy test results from the medical examiner's office, Batton told The Baltimore Sun on Tuesday.

"I just want to put my daughter to rest," said Darryl D. Parker, the child's father, in an interview at his home in the 600 block of Harwood Ave. in North Baltimore, about four miles from where the two bodies were discovered. "I just want my baby." Police had initially spelled the young girl's name as Dariel.

Parker said that his daughter stayed with him every weekend and occasionally during the week. He said Avery and Darry'el had been staying in the Loch Bend Drive apartment since around March this year and that he would pick up and drop off his daughter at that address. His relationship with Avery ended several years ago, he said.

The last time he saw his daughter was just over a week ago, on Father's Day, Parker said. Darry'el turned 4 on May 22, and attended Head Start.

"She was indescribable," Parker said of his daughter. "She was just amazing. She was so smart. She was just amazing."

On Tuesday morning, investigators were at the Welcome Inn Extended Stay Apartments complex on Loch Bend Drive and were seen going in and out of the building. Police forensic vans were parked in an alley behind the apartment where investigators were photographing and examining a window on the first floor.
