Raymond Lynde, 33, has been sentenced to 51 years to life in prison for killing Ariel Burquez, 23, the San Diego County District Attorney's Office announced earlier this week. The since-convicted man then stabbed the victim 28 times, "leaving him for dead." "This was a savage murder that was motivated by animosity and revenge," San Diego County District Attorney Summer Stephan said. We're grateful to our law enforcement colleagues in Mexico for their help in bringing the defendant back to San Diego to be held accountable for his vicious crime." Lynde reportedly admitted that he stabbed Burquez but claimed he did it in self-defense.
