Quick arrest in murder of 9-year-old girl in suburban Phila.

(CBS/KYW) SOUDERTON, Pa. - A 24-year-old man is being held without bail on first degree murder, kidnapping and sexual assault charges in connection with the murder of his 9-year-old neighbor, Skyler Kauffman of Souderton, Pa.

Montgomery County District Attorney Risa Vetri Ferman says James Troutman was Tuesday arrested after a detective noticed what appeared to be blood on Troutman's shoes.

"As we were searching for her, one of our detectives came across a man here who had what appeared to be blood on his shoes," said Vetri Ferman. "It was that sighting and discovery that led police to begin to question that individual."

According to court documents, Troutman told detectives he used his hands to choke Skyler Kauffman to death in the basement of the apartment building at Second and Chestnut streets, in the suburban Philadelphia community. He told police, "it was like a white out and he snapped."

After he allegedly murdered her, court documents show he told police he put Skylar's body in a dumpster.

Authorities say the girl's family reported her missing Monday night after she didn't return home from playing with friends in the parking lot of her apartment complex.

Souderton Police Chief James Leary says that during the investigation, police started interviewing a man who lives in that same apartment complex and gathered an overwhelming amount of physical evidence against the suspect.

"The child obviously struggled and as a result of that, she lost her life," Leary says. "We have recovered evidence at the scene that we will be able to link to the perpetrator."

"It appears from everything that we know that the crime took place very quickly and the body was disposed of very quickly and I can't say there was anything anyone else could have done that would have been able to prevent this tragic event," said Vetri Ferman.
