By Helen Pow PUBLISHED: 10:38 EST, 26 September 2013 | UPDATED: 17:25 EST, 26 September 2013 A Florida mother says she's cracked her son's murder case eight years after his death was deemed an accident. Judy Weaver worked tirelessly to get to the bottom of what happened on the rainy June day in 2005 when her son Ronnie Johnson, 34, was fatally injured. She was told he died after falling off his bike and hitting his head on a curb but that explanation didn't add up. This week, thanks to her detective work, Jason Gailey, has been arrested and charged with Johnson's murder. Police now say he struck Johnson in the head with a handgun when he tried to stop a fight. The impact saw the man fall to the ground and hit the concrete.
