An El Dorado County woman has pleaded guilty to murdering her husband and attempting to kill her co-defendant, the El Dorado County District Attorney's Office says. Patricia Presba, 48, entered the guilty pleas in El Dorado Superior Court last week. She is scheduled for sentencing March 5. According to prosecutors, Presba and her lover, Jaime Ramos, 22, killed her husband, Ron Presba, 54. Firefighters battling a wildland fire along Highway 193 near Kelsey found Ron Presba's body June 25, 2008, inside a charred sport-utility vehicle in a ravine.
