In the early hours of May 12, 2007, Maggie Haines, who was awakened by "sounds of struggle" in the middle of the night and "smelled blood", ran from the home and across the street to a neighbor who called 911 for help. Kreider had entered the Haines' home without force sometime around 2 a.m., stabbing Thomas and Lisa in their sleep, killing Thomas by stabbing him once in the heart and severely wounding Lisa. Kreider then went to Kevin's room and killed him after a brief struggle, inflicting over two dozen cuts and stab wounds, before returning to slit Lisa's throat, killing her, then escaping before the police could arrive. Kreider also slashed Tom across his left leg. On Monday May 14, during a
public briefing, police chief Neil Harkins stated that the residents "should be concerned", and that there is "a killer out there in the community". He also advised residents to lock their doors. During the investigation, which was mainly led by the
FBI, the entire neighborhood of Blossom Hill, where the Haines home was located, was "combed" over multiple times in search for any physical evidence. The authorities also went door-to-door to question the Haines' neighbours, and also searched the yards of nearby homes. The nature of the crime itself was baffling enough for law enforcement; a multiple murder in a quiet and essentially crimeless neighbourhood, with no signs of forced entry or
sexual assault. It was also revealed that nothing was taken from the home. On May 30, law enforcement concluded their final sweep of the Blossom Hill neighbourhood, and subsequently turned the Haines home over to the surviving members of the family. Around this time, the Lancaster County-Crime Stoppers established a hotline through which callers can give tips or information which could lead to a potential arrest of a killer or killers, with the reward posted at $1,000. == Legal proceedings ==
