Two arrested in 1988 case where body found near Petaluma

Wynetta Davis' death 25 years ago at the hands of unknown assailants might have forever gone without answers. The 26-year-old woman's body was found in a livestock water trough northwest of Petaluma. No suspects were identified.

More than two decades later, DNA evidence found by detectives who delved back into the 1988 case files led investigators to arrest two men who are now prime suspects in the slaying.

The case will now unfold in Sonoma County Superior Court, possibly bringing closure to the Davis family if the men are found guilty in the killing.

“I want to know why ... why,” said Davis' eldest sister, Marilyn Davis Jones, 57, of Vallejo. “I can't imagine her doing anything to them in the first place to make them want to kill her.”

Her other sister, Carlene Davis Taylor, 56, of Houston said that not having answers pained her family over the years. She wanted to call “Most Wanted” TV shows to raise awareness about her sister's case, but without suspects there was nothing she could do.

“I'm so grateful,” the case is moving forward, Taylor said. “We were best friends.”

The Sonoma County Sheriff's Office announced Wednesday that Josafat Presencion, 47, and Fausto Chavez, 49, were in custody at the Sonoma County Jail on suspicion of Davis' murder.

Presencion and Chavez pleaded not guilty Aug. 16.

The men, both Mexican nationals, were living in Vallejo in 1988, as was Davis, Sgt. Carlos Basurto said.

Davis lived on Grant Street in south Vallejo with her mother, Mary Davis, and two sons, aged about 2 and 5, her sisters said. Her sisters lived across the street.

On May 11, 1988, Davis left the house as night fell to buy diapers at a bodega around the corner, according to her family. Taylor said she ran out of the house to join Davis a few minutes later, but her sister was gone.

“I ran over to the store and said, 'Did you see my sister?' Taylor said. “He said, 'She didn't come in here.'”
