LENEXA, Kan. — Investigators found pipe bombs and a GPS tracking device in a car outside a Lenexa home where police say a gunman killed his ex-girlfriend and a man she was dating, then himself.
Television station WDAF reports that investigators also found a so-called ghost gun and other weapons inside the home where 22-year-old Sara Beck and 20-year-old John Williamson were killed Sunday. Police say the gunman was 37-year-old Dustin Johnson, of Belton, Missouri, who also killed himself. Court documents say Johnson was wearing a tactical vest when his body was found and that police found an assault rifle near him that had been constructed from various parts.
Lenexa police said they believe Johnson was using the tracking device to keep tabs on his ex-girlfriend.
