Police say Troutman took Skyler down two short sets of stairs to the basement where he raped the 9-year-old and killed her.
Heather was in the apartment above and heard screams, thinking they were coming from the apartment above hers.
"It's not unusual to hear screaming, laughter, on the occasion if a child is throwing a tantrum, telling their parents 'no,'" Clemens said.
Clemens says a while later, Troutman returned home and said he had been exercising at the track.
"He was very sweaty and he was covered in what looked like mud to me, dried mud, on his clothing from his chest down to his shoes," Clemens said.
She now knows it was blood, not mud.
Earlier on Wednesday, the Montgomery County coroner released the
official cause of death for Skyler Kauffman.
According to Coroner Walter Hofman, Skyler died of asphyxia and multiple blunt force injuries, ruling her death as a homicide.
