Police search home following double homicide at Great Wolf Lodge amid hunt for motive

Metallica Harrison is accused of killing her husband and 3-year-old son.

Authorities searched the Pennsylvania home of a family at the center of a double homicide at a Poconos resort as they tried to find a motive for why a woman allegedly killed her husband and 3-year-old son before trying to take her own life, according to court filings.

Police responding to a call for a suicidal caller found the two victims -- Charles Harrison and his son -- dead on mattresses, according to the criminal complaint. Harrison had been stabbed multiple times in the chest, while his son, identified in the complaint as T.H., appeared to have a single stab wound to his chest, according to the complaint.

The 911 caller -- identified in the complaint as 27-year-old Metallica Rose Harrison of Towanda -- was charged with two counts of homicide in connection with the deaths, according to the complaint.

A "large butcher kitchen knife" and a smaller knife were found in the bathroom, according to the complaint. Resort staff confirmed that the knives, which had teal handles, did not belong to the lodge, according to the complaint.

The family had been staying at the family resort since Sept. 21 and, after extending their stay, were slated to check out on Tuesday, according to the complaint.

"It is common for individuals in these scenarios to document their homicidal and suicidal ideation's via hand writings or electronics prior to, during and after the act has taken place," the application stated.

Officers were additionally seeking financial information and insight into why the family had left their home and had been staying at the resort for the past three weeks, according to the application.

Police ultimately seized nearly a dozen "teal knives" from the home, as well as a safe, a journal, a financial notebook, a laptop and other items, according to a court filing on the inventory.

Amid the investigation, the victims' family members described the suspect to police as "dominant" and "controlling" and that she had "isolated" them from the father and son, according to the search warrant application. One family member also claimed that Harrison was "resentful" toward her son because she "never wanted to get pregnant" and had made statements about the toddler "taking away one-on-one time between her and Charles," according to the application.

Harrison was denied bail during her arraignment on Tuesday, police said. She is in custody awaiting a preliminary hearing scheduled for Oct. 21. The online court docket does not list any attorney information for her at this time.
