Authorities searched a Pennsylvania home on Wednesday as they investigate the deaths of a man and his young son at a Great Wolf Lodge, seeking to understand the motive behind the violent domestic incident. The investigation is centered on Metallica Rose Harrison, who is accused of killing her husband, Charles Harrison, and their 3-year-old son.

The tragedy unfolded Monday in a room at the Great Wolf Lodge in Scotrun, Pocono Township. Police were initially dispatched after a 911 call from Harrison, who reportedly made statements indicating suicidal intent and referencing the deaths of her husband and son.

Upon arrival, officers discovered Charles Harrison and the child, identified in court documents as T.H., deceased on mattresses. The criminal complaint states Charles Harrison sustained multiple stab wounds to the chest, while his son had a single stab wound to the chest. Two knives, a large butcher knife and a smaller one, were found in the bathroom and did not belong to the resort.

Metallica Rose Harrison, 27, of Towanda, has been charged with two counts of homicide. During the 911 call, she allegedly stated she was too weak to harm herself and needed help dying, adding that her husband and son were "already gone in the bed."

Investigators are looking for evidence that could shed light on the motive for the killings and Harrison's actions. The family had been staying at the resort since September 21 and had extended their stay, with a checkout date of Tuesday.

A search warrant executed at the family's home in Towanda aimed to uncover writings or electronic records that might document suicidal or homicidal ideation. Authorities also sought financial information and details regarding the family's extended stay at the resort.

During the search of the Towanda home, police reportedly seized nearly a dozen knives with teal handles, consistent with those found at the crime scene, along with a safe, a journal, a financial notebook, and a laptop. The items are expected to provide further insight into the circumstances leading up to the deaths.

The investigation into the motive continues as authorities piece together the events that led to this double homicide at the family resort. No further details regarding potential motivations have been publicly released.
