The Miami-Dade Police Department issued no new information yesterday concerning Washington Redskins safety Sean Taylor, with two police sources saying that he remained a "person of interest" in a case involving a shooting Wednesday night and that, as of yesterday afternoon, he had yet to submit to questioning. On Friday, police spokesmen confirmed that Taylor was someone they were seeking to speak to about this case but, with the investigation ongoing, were unsure if he was a witness, victim or suspect.Taylor's agent, Drew Rosenhaus, has not returned repeated phone calls for the past two days. Taylor's mother, Donna Junor, who said Friday that she had not heard from Taylor recently, was unable to be reached by telephone yesterday.The Redskins have yet to acknowledge the situation in any form, issuing no statements and returning no phone calls. NFL representatives said they were deferring to police officials with the case still under investigation and said they had no information on Taylor's whereabouts.Police officials have said no one was injured in the incident being investigated. One police source said Friday that Taylor, 22, and a friend were at the scene of a crime Wednesday night where shots were fired into a stolen vehicle in a residential area, but the nature of their role in the case was unclear. Taylor was one of several people police were trying to contact to gather more information about what may have occurred.A Miami-Dade detective said yesterday that the robbery division was investigating the case, while the department's public information office, which handles inquires from the media, was closed for the weekend. Two police sources said that, given Taylor's high profile, the department would likely issue a statement if or when he was questioned, and that had not occurred as of last evening.Police investigators attempting to find Taylor have contacted his family and league officials, but several of Taylor's family members said Friday they did not know where he has been. Taylor has spent much of the offseason in South Florida, where he makes his home, and has elected not to participate in the team's voluntary workouts and practices, a decision with which Coach Joe Gibbs has expressed disappointment on numerous occasions.
