(AP) — Prosecutors in Southern California say a father from Nebraska has been convicted of murdering a man who got into a fight with his daughter.

District attorney’s spokeswoman Farrah Emami (FAHR’-uh ee-MAH’-mee) says 41-year-old Cesar Marta of Omaha was convicted Tuesday of second-degree murder.

Prosecutors say Marta, of Omaha, was visiting family in 2010 when he beat 27-year-old Cesar Gutierrez-Hernandez as he was leaving his Santa Ana home, a month after Hernandez fought with Marta’s daughter.

An unknown accomplice of Marta’s held Hernandez’s friends back at knifepoint then stabbed Hernandez, who later died at a hospital.

When Marta was identified as a suspect, he was in federal custody in Council Bluffs, Iowa on immigration charges. He was extradited to California to face trial.

He is due for sentencing Aug. 9.
