By Sid Saraf, FOXSports.com Officials say the step-grandfather of Buffalo Bills running back CJ Spiller went on a shooting spree on North Florida on Saturday, killing two people and injuring two before ultimately killing himself. Florida TV station WCJB reports that Hubert Allen Jr. shot and injured David Griffis at Pritchett Trucking Company, where he worked for more than 30 years. He then went to the company owner's farm and killed two people: Rolando Gonzales Delgado and the owner Marvin Pritchett. FOX Sports has confirmed that Allen was the shooter. Allen then shot another person, Lewis Mabrey, Jr., before going home and killing himself. Mabrey is in good condition after undergoing surgery for a broken arm. The sheriff of Lake Butler, Fla. says Allen knew all of the victims and had worked with all of them in the past. Spiller played in Buffalo's preseason game against the Redskins on Saturday and was injured during a touchdown run in the first quarter. He later returned to the game right before halftime, despite noticeably limping.
