(AP) A former Florida trucking company employee who went on a weekend shooting rampage left a handwritten note that listed his four victims, two of whom died, investigators said Monday.
Union County sheriff's Lt. Lyn Williams said three days of interviews with people who knew 72-year-old Hubert Allen Jr. haven't turned up a motive for Saturday's shooting spree centered around Pritchett Trucking Inc., but his targets weren't random.
"Further investigation revealed by a handwritten note at Allen's house that this was a premeditated event targeting these individuals," according to a news release. "The note did not reveal a motive."
The Rev. Patrick Maxwell of Victory Christian Center said even family members do not know why Allen went on the shooting spree. Allen's daughter and grandchildren are members of Maxwell's church and went to their home on the day of the shootings to comfort and counsel them.
"We all hope and pray that some answers come out, but unfortunately the only person that knows is no longer with us. He slipped into eternity," Maxwell said.
On Saturday, Allen drove to a location owned by his former boss, Marvin Pritchett, the trucking company's founder. He shot and killed former co-worker Rolando Gonzalez-Delgado, 28, around 9 a.m., then went a short distance and killed Pritchett, 80, who began the company in 1980. Allen, at one time, was considered his top assistant.
A few minutes later, Allen pulled over where another former co-worker was driving a farm tractor, exchanged words with him and fired a shotgun, authorities said. The victim, 66-year-old Lewis Mabrey Jr., was in good condition.
Allen then went to the company's headquarters in Lake Butler and shot 44-year-old David Griffis in the stomach, the sheriff's office said. Griffis was in critical condition.
Allen killed himself at his nearby home. Deputies recovered a .22-caliber rifle, a .410-small-bore shotgun and an unfired .32-caliber handgun.
Allen was the step-grandfather of Buffalo Bills running back C.J. Spiller.
Bills coach Doug Marrone said Spiller was excused from the team to go to Florida.
"Our thoughts and prayers go out to the victims as well as, you know, C.J. and his family in this situation," Marrone said Monday. "We're in communication. I don't have any answer of when he's going to come back."
Pritchett Trucking's website said it employs 400 people and owns hundreds of vehicles that operate nationwide.
