The Garfield child care facility where police said a 7-year-old girl killed an infant this month has closed, according to state officials.

On Wednesday, Loretta Bray, operator of Bray's Family Day Care on Dearborn Street, handed her certificate of registration over to an inspector from the state Department of Public Welfare who was visiting the facility, which is also Ms. Bray's home.

"She's closed," said Jennifer R. Lau, director of the licensing bureau of DPW's Office of Child Development and Early Learning. "We don't have the legal authority to enter."

DPW officials have made several visits to the center since June 6, when, according to police, the 7-year-old girl removed 10-month-old Marcia Poston from her baby chair and threw her to the floor twice.

The 7-year-old, who is now in the custody of Allegheny County's Office of Children, Youth and Families, is Ms. Bray's granddaughter.

Ms. Bray was out of the house at the time, running an errand. Her daughter, Ashley Swann, was upstairs changing another child's diapers.

The Allegheny County medical examiner's office has ruled the infant's death a homicide. Police are still investigating, and both Ms. Bray and Ms. Swann could face charges.

There were five children in the home at the time of the incident. Investigators said parents of the other children didn't have any complaints about Ms. Bray or the child care facility.

The business was classified as a "family child care home," meaning it could have no more than six unrelated children at one time.

The state doesn't inspect such facilities annually, as it does with larger care centers. Ms. Bray's home, which opened in 1999, had last been inspected in 2004. There were minor violations, and they were corrected, according to state records.

DPW sent inspectors the day after Marcia's death and on at least two other days, Ms. Lau said. Ms. Bray hasn't had any children at the home since the incident. Now inspectors won't be going back.

"Once [she] gives up that certificate, we have no legal recourse," Ms. Lau said.
