Pasco County deputies say a love triangle turned deadly last week after a Port Richey man allegedly battered his girlfriend and stabbed to death another man with whom she had been having a sexual relationship.
According to authorities, Brendan Michael Sigismondi and an unnamed female were in a relationship and had been cohabiting for about two months when Sigismondi discovered that she was in a sexual relationship with Thomas Christopher Blow.
Police say the 32-year-old Sigismondi told his girlfriend that he expressed to her that he would kill the 36-year-old Blow before he grasped her hair and drug her by it into their bedroom. His girlfriend told police that he expressed his immense displeasure at the situation before exiting the residence with a in hand.
Investigators say that Sigismondi told them he approached Blow, and Blow punched him. Sigismondi allegedly responded by stabbing Blow a single time before departing the scene.
Meanwhile, Blow laid dying in the middle of Embassy Boulevard. A passerby alerted a passing deputy who, in turn, dispatched paramedics to the scene. Their efforts were in vain however, and Blow expired where he lay.
Sigismondi was arrested later that day and booked into the Pasco County Jail on one count each of first-degree murder, domestic battery, grand theft, and a handful of forgery charges. The New York native is being held without bond.
