MIAMI, Florida (CNN) -- Four men have been arrested in connection with the shooting death of NFL player Sean Taylor, authorities announced Friday evening.
The suspects were identified as Venjah K. Hunte, 20; Eric Rivera Jr., 17; Jason Scott Mitchell, 17; and Charles Kendrick Lee Wardlow, 18.
Additional arrests are possible, Parker said.
"The key to solving this case was citizen's tips," he said.
Taylor, 24, died Tuesday, a day after he was shot during an apparent burglary at his Miami home.
The police investigation revealed the suspects thought the house was empty, Parker said.
"They were certainly not looking to go there and kill anyone," he said. "They were expecting a residence that was not occupied, so murder or shooting someone was not their initial motive. ... Their obvious motive was to go there and steal the contents of the house."
The men knew Taylor lived at the house, Parker said.
At 1:45 a.m. Monday, Taylor's girlfriend, Jackie Garcia, called 911 and said someone had been shot.
Authorities have said she told police she was hiding under the bedding during the attack.
Garcia did not see what happened and could not provide a suspect description, Parker told reporters on Wednesday.
Police said Garcia and Taylor were awakened by noise in the living room, and that Taylor got up and locked the bedroom door, but the door was kicked in and two shots were fired, one striking him in the leg.
Garcia tried to call 911 but was unable to, and used her cell phone instead, police said. There was no evidence the line had been cut, Parker said Wednesday.
A break-in was also reported eight days earlier, Miami-Dade police said.
A police report said someone forced a window open and left a kitchen knife on a bed. Several drawers and a bedroom safe were searched during the break-in, according to the report.
Taylor was home unexpectedly because of an injury, his former attorney, Richard Sharpstein, told reporters Tuesday. "I think he was surprised or they were surprised to find him there," he said.
Taylor spent four years with the Washington Redskins, but had been out with a sprained right knee. He did not play in Sunday's game against Tampa Bay.
Taylor was a first-round pick in the 2004 draft, according to his team's web site.
