SAN PABLO -- Police on Friday released information about a 54-year-old San Pablo woman who investigators say is disabled and depressed and has been missing for nearly six weeks.

Doretha Loretta Robinson was last seen Saturday, Nov. 24, at a family party in the East Bay, police said. But family members waited until Christmas Day -- a month later -- to report her missing, police said. Family members are not close, but after not hearing from her for four weeks called police, said Lt. Jeff Palmieri.

Police said Robinson has not disappeared before.

Palmieri said police waited 10 days to release information about her disappearance until a second search of her home was completed Thursday. Police said the house is cluttered and in disarray and there was a chance she might not have been seen on the first search of the home.

Robinson is currently taking medication for pain in her feet and uses a cane to get around, police said.

Police said her cane was found inside her house and her car was found parked in her garage. Police said the woman, who also suffers from depression, usually takes her dog with her everywhere she goes. But searchers found the dog in the home and without food or water. It was not clear how long the dog had been without food or water. The dog was taken into care by animal control, police said.

Robinson is described as a black woman, 5 feet 10 inches and weighing roughly 149 pounds. She has brown eyes and brown hair.

Anyone who knows her whereabouts or has had contact with Robinson should call Detective Dan Wiegers the San Pablo Police Department at 510-215-3130, or after hours at 510-233-1214. Reference Case No. 12-33947.
