The Southwestern Regional Police Department arrested Ray Heck Sr., 59, at 6 p.m. at his Spring Grove home.
CBS-21 reports Heck is charged with the homicide death of 24-year-old Samantha Stein.
She was found dead at her home just after 7 a.m. on Sunday morning. Three children were at the home at the time, but none were harmed.
Heck lived less than a block away from Stein, and the two are said to have been acquaintances.
Motive for the crime is still unknown. The most recent report confirms that Stein died from stab wounds.
Officers found a video showing a person entering and leaving the victim's home. Additionally, officers located evidence discarded by Heck in several different locations, including dumpsters and a wooded area.
