A Louisiana woman who was previously facing fraud and other charges after the death of sports reporter Adan Manzano has now been charged with second-degree murder in his death, the Kenner Police Department announced Tuesday.

Authorities also announced Manzano's cause of death and the arrest of an alleged accomplice of the suspect in Florida.

New evidence directly linking Danette Colbert to Adan Manzano's death allowed detectives to obtain an arrest warrant for an upgraded charge to murder, police said.
