A 74-year-old Maine man faces charges in the alleged shooting deaths of two of his tenants, Derrick Thompson and Thompson’s girlfriend, Alivia Welch. James Pak was arrested Saturday night at his home in Biddleford, Maine, after a three-hour standoff. Police had been called to the home earlier in the day during a dispute between Pak and his tenants over cars being parked in the driveway during a snowstorm. Minutes after officers left the house, they received a call from Thompson’s mother reporting the shootings. Neighbors said Pak is known for his short temper.
