Davis appeals the trial court's denial of his motion for new trial, following his conviction for arson in the second degree. The particulars of the offense are that Davis burned a laundromat owned and operated by Detective Williams of the City of Cordele. Detective Williams conducted his own investigation of the matter; the arrest warrant was issued by a justice of the peace who was also an antique dealer and a police dispatcher. Held: 2. It was not error to deny motion for new trial made on the grounds that appellant was denied a right to a preliminary hearing. State v. Middlebrooks, 236 Ga. 52 (222 SE2d 343). |
