Shreveport detectives have been able to develop 28-year-old LaReginald Doyle as one of the men they think pistol-whipped and robbed another man in his house on East 70th Street in August of last year. So they've obtained an arrest warrant charging him with one count of armed robbery and setting his bond at $100,000. Police say Doyle's last known address was in the 19-hundred block of Patzman Street. If you know where police can find him, call Crime Stoppers of Shreveport and Caddo Parish.
