He said evidence at Taylor's home indicates one or more intruders barged into the house early Monday in an attempted burglary. After a confrontation inside the home, Taylor was shot once in the upper leg and died early Tuesday after losing a tremendous amount of blood.
Taylor's family has scheduled a funeral service for 11 a.m. Monday at Pharmed Arena at Florida International University in Miami.
Police have no suspects and have asked the public to come forward with any information.
The player's father, Pedro Taylor, and other members of his family traveled to Ashburn, Va., to meet with his teammates, who are preparing for Sunday's game against the Buffalo Bills.
"Many of these guys were wondering, 'How in the world am I going to go out and do this on Sunday?' " said Brett Fuller, the team chaplain. "And when Mr. Taylor stood up and said go out and win these next five and make it to the playoffs, we felt a surge in the room, that he almost gave us permission to play well."
Meanwhile, Rolle said, "This was not the first incident. They've been targeting him for three years now."
Rolle said many former "friends" had it in for Taylor, who was trying to build a more stable life. "He really didn't say too much," Rolle said, "but I know he lived his life pretty much scared every day of his life when he was down in Miami because those people were targeting him. At least, he's got peace now."
Rolle said he hadn't talked to Taylor in a while, and that the Redskin had withdrawn from the crowd he hung around with to build a new life with his girlfriend and young daughter.
"They say it was a burglary. It absolutely was not a burglary," he said. "Sean, he had a large group of friends, and he no longer hung out with those friends, so you never know where this came from."
