A 9-year-old girl who disappeared while playing outside her suburban Philadelphia apartment complex has been found dead, and a neighbor is in custody, police said Tuesday.

State police issued an Amber Alert on Monday night for Skylar Kauffman when she didn't come home for dinner after playing with her friends in the complex's parking lot in the small town of Souderton.

The girl's body was discovered a few hours later in a nearby trash bin. Kauffman would have turned 10 next month.

There's an "overwhelming" amount of physical evidence linking the suspect to Kauffman's death, Souderton police Chief James Leary said.

Leary said a significant amount of blood and a trail with some of Kauffman's belongings, including her boots, led police from the apartment building's basement to the area where her body was found wrapped in a blanket, MyFoxPhilly.com reports. 

Leary did not release the name of the male suspect, who lived in the same complex as the victim. The Times-Herald of Norristown reports the 25-year-old man is expected to be arraigned on charges Tuesday afternoon.

Souderton Area School District Superintendent Frederick C. Johnson posted a statement on the district's website saying grief counselors were available for Kauffman's classmates at E. Merton Crouthamel Elementary School.

"There is no greater loss than that of a child," Johnson wrote. "Words are inadequate to express our sorrow to the family for their tragic loss."

The Times-Herald reports two prayer vigils were scheduled for Tuesday evening at a church and at the girl's apartment complex in Souderton, about 30 miles north of Philadelphia.
