, 74, of Biddeford was arrested on Saturday night after a three-hour standoff and charged with two counts of murder for the shooting deaths of 19-year-old Derrick Thompson and his girlfriend, 18-year-old Alivia Welch. Thompson's mother, 44-year-old Susan Johnson, was also shot and was rushed to Maine Medical Center for treatment.
Public Safety spokesman Steve McCausland told reporters that Johnson called 911 shortly after 7 p.m. to report the fatal shootings. Officers from a state police tactical force then rescued her and a 7-year-old child, who was not harmed, from the two-unit home that Pak had rented one of the units to Johnson since October.
Maine State Police Sgt. Mark Holmquist said that the shooting stemmed from a dispute over where cars should be parked in order to facilitate snow removal. Holmquist told reporters that Biddeford police had responded to a call about a dispute at the home but left. Gunshots were then reported just minutes after the officers departed from the scene.
