Update---The jury in the trial of Tyler Ostertag of Camarillo found him guilty of second degree murder Thursday.
Jury deliberations began Monday afternoon.
He faces more than 50-years-to-life in prison when he is sentenced on May 10th .
Before that the court must make a ruling regarding his prior convictions.
Ostertag was convicted of the stabbing death of a Camarillo High School football player during an altercation outside a fast food restaurant on August 31, 2015.
The altercation and stabbing happened outside the Taco Bell on Flynn Road in Camarillo.
Prosecutors argued that then 20-year-old Tyler Ostertag of Camarillo killed 16-year-old Daniel Morales of Camarillo using a knife and it was murder.
But the defense claimed Ostertag's actions were self defense.
While the jury decided against first degree murder, they rejected the self defense claim and convicted Ostertag of second degree murder.
The incident was witnessed by several people including friends of both the defendant and victim.
There was reportedly a history of bad blood between the two and both young men were accused of having a tendency to be violent.
After the stabbing, Ostertag fled to Riverside County where he was arrested that night.
Morales died at the hospital from his wounds.
After closing arguments Monday, the jury began its deliberations and then recessed for the day.
They continued deliberations Tuesday and Wednesday and announced their verdict Thursday morning.
