A young couple was shot dead by their landlord after arguing with him over parking their cars in his driveway, police say.
Derrick Thompson, 19, and Alivia Welch, 18, were killed in their apartment on Saturday just three minutes after police left the property in Biddeford, Maine.
Officers believed they had quelled an argument between the tenants and James Pak, who owned the duxplex, authorities say.
Pak, a 74-year-old Korean War orphan and local business owner, lived in one half of the duplex and rented out the other half. Neighbors described him as a 'horrible landlord,' with an short temper who spied on the people who rented from him.
Pak also shot and wounded Mr Thompson's mother, Susan Johnson, 44, who was also living in the apartment with her six-year-old son, police say.
The young boy was found hiding in a back bedroom. He and Ms Johnson, as well as Pak's wife, were rescued by officers shortly after the shooting, the Portland Press Herald reports.
