BATON ROUGE - After a man was found dead on the Huey P. Long Bridge on Thursday night, detectives say he may have died before being struck by a vehicle there. 

The East Baton Rouge Sheriff's Office said the man, who was identified Friday morning as 41-year-old Gerard Nicholas Richard, appeared to have been struck by a vehicle at some point, but that was not necessarily his cause of death. 

His cause of death is pending further investigation. Deputies say they are investigating Richard's death as a homicide. 

It was not clear how he ended up on the bridge. 

This is a developing story.
