Fears for death-row case investigator who vanished after going to meet mysterious caller who claimed they had information on her missing pet dog Ginny

An Oakland single mother has disappeared after being lured into meeting someone who promised her information on her missing dog.



Sandra Coke, 50, a capital case investigator for death row prisoners, was last seen at home on Sunday evening by her 15-year-old daughter.



A spokesman for the family said that Coke left the house after receiving a call about her beloved King Charles spaniel named Ginny, who was stolen from her home in May.

On Tuesday evening, Coke's car, a 2007 Mini Cooper was found on the 800 block of 32nd street, around two miles from her home.



And later on Tuesday, Oakland police located Coke's work and personal cell phones - which were recovered in separate locations.



Coke is a capital case investigator for the Office of the Federal Public Defender in Eastern District of California and police are not sure if her job is a reason for her disappearance.

When asked if her job might have had anything to do with her disappearance, Coke’s sister Tanya Coke said they don’t know but it could be possible.

'We just don’t know,' said Tanya Coke to KTVU.com.

'Her work takes her out in the field, interviewing all kinds of people from all walks of life. We don’t know if someone she met on the job could be involved in her disappearance.'

Last Seen: Sandra was last seen by her 15-year-old daughter leaving their Oakland home at around 8 p.m. on Sunday to check on a top about her missing dog

Tanya Coke said that her niece told her that Sandra was going to meet someone who had phoned to say they had information on her missing dog.



'She was very attached to the dog and very concerned about trying to get her back,' said Joe Schlesinger, a friend for over 20 years to ABC News.

'We work on cases where there are all kinds of tragedies and it isn't the most popular work, but we have no reason to believe her disappearance has anything to do with the crimes she was investigating,' said Schlesinger.



'She was a committed, stable person that wouldn't just wander off.'

Missing: Coke's car was recovered at around 7.45 p.m. on Monday at 800 Blk of 32nd street close to her home at 600 Blk of Aileen St. One of her cell phones was found at San Pablo Avenue and the other at the junction of Wilson and McDonald Avenues

Speaking to ABC News, Schlesinger said that in the aftermath of Ginny's theft, single mother Sandra would post missing notices all over her neighborhood in an attempt to get her dog back.



A stranger at one point called Coke with information related to her pet.



'And said, 'I have information about your dog. How much is your dog worth to you?' And she still got nothing,' Sandra Coke's sister Tanya Coke told ABC Bay Area affiliate KGO.



On Wednesday, relatives and friends held a press conference to appeal for any information that could lead to the recovery of Coke.



'We're very worried. The circumstances seem very suspicious,' said Schlesinger.



'All we know is my sister is missing and we suspect foul play because this is unlike her,' said Coke's sister, Tanya Coke.
