OAKLAND (KRON) — An Alameda County Superior Court jury has found career criminal Randy Alana guilty of killing his girlfriend in Oakland of 2013.

It took jurors less than 2 hours to convict 58-year-old Alana of first degree murder in the death of his girlfriend, 50-year-old Sandra Coke.

Coke was a federal public defender who disappeared on August 4, 2013. She was found dead in a remote area of Vacaville five days later.

Along with the murder conviction, Alana was also found guilty of robbery for stealing items from Coke, vehicle theft for stealing her car, and grand theft for using her ATM card to get cash.

As his verdict was being read, Alana looked straight ahead, showing little emotion.

Prosecutor Colleen McMahon said in her closing argument earlier this week that Alana, who has 17 prior convictions, including one for manslaughter, likely killed Coke because she was ending their 20-year off-and-on relationship and told him she would no longer support him financially.

McMahon cited a large amount of circumstantial evidence in the lengthy trial, which included 84 witnesses. Alana’s defense attorney Al Wax said in his closing argument that prosecutors did not meet the burden of proof in the case.
