Just days before he was to have a preliminary hearing, the attorney for a man accused of killing a Point Loma victim declared April 30 he had a legal conflict and couldn’t represent the defendant. San Diego Superior Court Judge Timothy Walsh appointed a new attorney for Shane Brian Grattan, 56, who is accused of killing 45-year-old Darrin Joseph, whose body was found Jan. 19 in the 4900 block of North Harbor Drive. Joseph was homeless, but stayed in the Point Loma area. His body was found in some bushes near a parking lot and he apparently had some traumatic injuries. Grattan was arrested Feb. 8 on Garnet Avenue in Pacific Beach. The public defender wouldn’t say in open court the reason for the conflict, but legal conflicts often occur because of prior representation of witnesses whose background may be known to the public defender. Walsh appointed a lawyer with the alternate public defender agency. The May 4 preliminary hearing was postponed and rescheduled for June 6. If the new lawyer asks for more time to prepare, it will likely be granted. Grattan remains in the Vista Detention Facility on $1 million bail.
