Authorities say the Pennsylvania man suspected of killing Rebekah Byler, 23, in her own home in February was well-known in the area for his allegedly “odd behavior” and suspicious activities, including a possible late-night confrontation with Byler’s husband.
Byler, who was six-months pregnant at the time of her death, was found by her husband Andy Byler and the family’s driver Julie Warner on Feb. 26, according to a probable cause affidavit reviewed by PEOPLE. (Members of the Amish community have drivers as they don’t drive themselves).
