LAKE WORTH, Fla. – An 8-year-old girl who had been sexually assaulted and buried under rocks in a trash can was found alive yesterday by an officer searching a landfill, authorities said. A teenager was charged with attempted murder. The girl had minor injuries and was taken to a hospital, they said. Hospital officials declined to comment on her condition last night.

Milagro Cunningham, 17, who had been staying at the house of the girl’s godmother, was charged with attempted murder, sexual battery on a child under 12, and false imprisonment of a victim under 13 years old, police said. The girl was found about seven hours after she was reported missing, but authorities were still trying to determine how long she had been inside the trash bin.

An Amber Alert had been issued early yesterday. Police Sergeant Mike Hall was scouring the landfill for the girl early yesterday when he looked inside the trash bin and saw a yellow recycling container with a lid on it. When he opened the lid, he saw “saw a bunch of rocks, a foot, and a hand,” Sergeant Dan Boland said. Sergeant Hall then yelled out to see if the child was alive, alerting other officers to the discovery. A police lieutenant saw the girl’s finger move and officers began pulling rocks off her, Sergeant Boland said.

“It certainly was a miracle that we found this girl alive,” Sergeant Boland said, adding that the girl was able to talk to authorities after she was removed from the container. The girl had been staying overnight at her godmother’s house when she was abducted, Sergeant Boland said. Mr. Cunningham had lived there for about four months, but he was not related to the girl, police said.

Mr. Cunningham was questioned by police early yesterday after the girl was reported missing and told them she may have been abducted by two men in a station wagon, Sergeant Boland said. Detectives re-interviewed Mr. Cunningham when the girl was found and the teen eventually confessed, Sergeant Boland said.
