CARLISLE, OH (FOX19 NOW) - The Warren County home where a newborn's body was found buried in a shallow grave is now being treated as a crime scene, authorities announced Monday.
Investigators, including some wearing gloves used to collect evidence, searched the home on Eagle Ridge Drive and seized items including what appeared to be a large portion of carpet FOX19 NOW spotted them carrying outside late Monday.
At least two vehicles from the Warren County Sheriff's Office and two Carlisle police cruisers were at the residence for seven hours, leaving at 1 a.m. Tuesday.
Last week, one of the residents, 18-year-old Brooke "Skylar" Richardson, was charged with one count of reckless homicide after the remains were found buried in her backyard on July 14.
The infant was born alive sometime in May, according to court documents show and prosecutors.
The baby's cause and time of death remain a mystery, but police describe the case an ongoing investigation.
The newborn's remains likely were buried about three months, according to Warren County Detective Lieutenant Jon Faine.
Investigators were last at the home Thursday to collect samples in and around a fire pit.
Authorities announced Richardson's arrest several hours later.
A warrant filed Thursday in Franklin Municipal Court claims Richardson did "recklessly cause the death of another or the unlawful termination of another's pregnancy" around May 7.
She pleaded not guilty in her first court appearance Friday.
Richardson just graduated high school and plans to attend the University of Cincinnati, according to her attorney, Charlie Rittgers. The cheerleader also worked at the YMCA with children with special needs.
"She didn't drink, she wasn't a partier or a smoker. By all measures a very good girl," Rittgers said.
Forensic anthropologists at the Miami Valley Regional Crime Laboratory are analyzing the human remains.
