Rayna Elizabeth Hoffman-Ramos, 61, of Dewey, Washington County, Oklahoma, United States has been arrested. She is the only suspect in the case involving the murder of a Taiwanese-American man named Shu Ming Tang, the then owner of the Devonshire Little Store, a mom-and-pop shop in San Carlos, San Mateo County, California, USA.

Just before 1:00 p.m. on April 26, 1993, Hoffman-Ramos allegedly shot Tang in the chest inside the store. She was reportedly last seen leaving the store in a faded blue 1970s station wagon.

Tang was rushed to the hospital, where he later died. In July 1993, the Devonshire Little Store was sold to Chung Sun, who is also Taiwanese-American.

At the time of Tang’s killing, Hoffman-Ramos was a San Mateo County resident. The case went cold but in 2018, detectives with San Mateo County Sheriff’s Office reviewed the case, used forensic technology and identified her as a suspect.

On March 16, 2022, the detectives conducted a simultaneous operation in Sacramento County, California and Dewey and discovered additional supporting evidence. That day, Hoffman-Ramos was arrested in Dewey.

Officers found in Hoffman-Ramos’s Dewey residence a journal with a page in it titled “Things I Regret.” One of the items in the list was the killing of a “Korean” man in San Carlos in 1993.

Hoffman-Ramos is being held without bail in Washington County Jail in Bartlesville, Oklahoma while awaiting extradition to San Mateo County. Tang’s family has been informed of her arrest.

It was not the first time Hoffman-Ramos was arrested. He had multiple arrested in the Sacramento area for drug related and other nonviolent offenses years after the murder of Tang.
