9-year-old Skyler Kauffman and her alleged killer had run-in 3 weeks before her death, report says

(CBS/KYW) SOUDERTON, Pa. - James Troutman, the man charged with the murder, kidnapping and sexual assault of his 9-year-old neighbor, Skyler Kauffman, invited Skyler and her friend to use his bathroom three weeks to the day before her death Monday night, a report says.

The girls went willingly into Troutman's home to use his bathroom at the Souderton Gardens Apartments , where they all lived, on April 18, according to court documents, reports The Philadelphia Inquirer.

When the girls went inside they saw pictures of naked women hanging from the walls. Troutman offered to show them his "bird," and when they realized that he had locked the apartment door behind them, they ran away and told their parents, the documents say, according to the Inquirer. .

Police said they had responded and interviewed Troutman, but they never charged him with any crime.

Troutman, 24, was arrested Tuesday after a detective noticed what appeared to be blood on his shoes. According to court documents, Troutman told detectives he used his hands to choke Skyler to death in the basement of the apartment building. After he allegedly murdered her, court documents show he told police he put Skyler's body in a dumpster.

Troutman is being held without bail on charges of first degree murder, kidnapping and sexual assault.
