San Joaquin Co Sheriff's detectives and FBI have learned that the true identity of murder victim Larry McNabney's wife is Laren Renee Sims, 36, of Massachusetts.

Sims is wanted by the FBI for unlawful flight to avoid prosecution. Murder charges were brought against her after autopsy results linked her with the death of her husband.

Sims is currently a fugitive from Florida in relationship to charges of burglary and credit card fraud. She's still on the loose and is still believed to be traveling with her 17-year-old daughter, Haylei Jordan.

Detectives in San Joaquin County said they believe Sims killed her husband of six years with a lethal dose of horse tranquilizer sometime after Sept. 10, when he was last seen at a Los Angeles County horse show.

Detectives said they believe his body was refrigerated for several months while his wife accumulated at least $500,000 by selling his property, cleaning out trust funds and forging checks at his law practice.

Then, in late December or early January, detectives said she buried him in a shallow grave in a San Joaquin County vineyard.

Police said Sims has used several Social Security numbers and several aliases. She was last seen in January leaving the couple's Lodi-area home. She has known ties to Florida and Nevada.
