Speedie Deaths Ruled Murder-Suicide

Investigators in Yellowstone believe they have come up with an answer to how Drew Speedie and his 13-year-old son, Brent, fell 200 feet to their deaths off the Gardner River Bridge just east of Mammoth Hot Springs in September 2005.
Though they say they'll never know exactly what transpired, the investigators have ruled the deaths a murder-suicide. They believe the 50-year-old Drew Speedie, a computer software engineer from Arizona, pushed his son from the bridge and then jumped off. Details of their investigation can be found here.
