MIAMI — Cleveland Browns wide receiver Donte' Stallworth was driving drunk when he struck and killed a pedestrian, according to published and broadcast reports Thursday.

WSVN-TV reported that unnamed sources with knowledge of the investigation said Stallworth's blood-alcohol level was between .08 and .16. The legal limit is .08. The Miami Herald also cited an unnamed source as saying that Stallworth's blood-alcohol level was above the legal limit.

The Miami Beach Police Department refused to confirm the reports. Ed Griffith, spokesman for Miami-Dade County prosecutor Katherine Fernandez Rundle, would say only that the investigation is focusing on whether alcohol was a factor in the death of 59-year-old Mario Reyes.

Reyes was struck and killed by a Bentley driven by Stallworth about 7 a.m. Saturday morning. Reyes, a crane operator, had just gotten off work and was trying to catch a bus when he was hit.

No charges have been filed against the 28-year-old Stallworth, who issued a statement Wednesday saying he was "grief stricken" over Reyes' death.

If Stallworth was drunk, he could be charged with DUI manslaughter which carries a maximum 15-year prison sentence.
