In a significant breakthrough, California authorities have apprehended a suspect in a decades-old cold case involving the mysterious disappearance of a mother who left behind her child and personal belongings. The Placer County Sheriff’s Office announced that 64-year-old James Lawhead Jr. was taken into custody in Bullhead City, Arizona, on Friday. He is now facing charges related to the 1991 kidnapping and murder of Cindy Wanner.

“This case stands out as one of the most infamous and brutal unsolved cases in Placer County,” stated Sheriff Wayne Woo. “We have tirelessly pursued justice for Cindy and her family, and we hope this arrest marks a step towards healing for those affected.”

Cindy Wanner was last seen on November 25, 1991, in her Granite Bay, California home. At the time, she was 35 years old and left behind her 11-month-old child in a highchair, along with her car, shoes, and coat.

Tragically, three weeks after her disappearance, Wanner’s body was discovered in a secluded area near Foresthill, situated approximately 40 miles from her residence.

Three weeks later, her body was found in a remote area near Foreshill, roughly 40 miles from her home. 

Authorities determined Wagner had been strangled.

The search for Wagner’s killer ran cold, until authorities submitted a final piece of evidence to the Contra Costa County Sheriff’s Office for DNA testing to name Lawhead as a suspect, officials said. 

Lawhead, who was 30 at the time of Wagner’s alleged murder, had been released from prison in 1991 after serving 11 years behind bars for sex crimes involving a child.

Authorities noted that he had seemingly vanished, pointing to a staggering lack of documentation involving his whereabouts that had not been updated since 2005. 

The revelation led authorities to determine Lawhead had likely assumed a new identity and, by working with local law enforcement agencies in areas where he was believed to have been living, investigators used facial recognition to find a match.

Detectives subsequently uncovered that Lawhead had been living in Bullhead City, Arizona, under the name Vincent Reynolds.

He was subsequently taken into custody with assistance from the Bullhead City Police Department and booked into an Arizona jail, according to authorities. He is expected to be extradited to Placer County to face charges.

The investigation also led to the arrest of Lawhead’s 71-year-old sister, Terry Lawhead Steele, authorities added.

Steele was arrested in South Carolina on Saturday on an accessory charge.

“Although Steele had spoken with law enforcement several times over the years, including with our detectives just weeks ago, and claimed she had not heard from her brother in more than 20 years, investigators discovered James Lawhead had been living in a home she owned,” authorities said. “Evidence also showed the two had remained in communication.” 

Authorities are now investigating whether Lawhead is responsible for similar crimes in the area, according to police.

It is not yet clear whether Lawhead has retained an attorney. 

“This arrest is a powerful reminder that time does not erase responsibility, and it does not diminish our commitment,” Placer County District Attorney Morgan Gire said. “Cold cases are not forgotten cases — they remain urgent, they remain personal, and they remain a promise we intend to keep.
