Fred Trayers (L) was going to leave his wife Jennifer (R) his mistress testified at trial.
The wife of a San Diego-based Navy doctor who stabbed her husband to death was sentenced Friday to 16 years in prison.
Jennifer Trayers was convicted of second degree murder with a deadly weapon.
Prosecutors had charged Trayers with first degree murder after she stabbed her husband Fred Trayers in the back of the head inside the couple's North Park condo in December 2010.
She told jurors she initially approached her husband with a knife intending to kill herself but was provoked into the attack by her husband.
She testified she "blacked out" after the first stab.
Fred Trayers' mother submitted a letter to the court asking for mercy, saying she has lost and mourns both her son and her daughter-in-law.
The 16 years to life sentencing was the maximum afforded in the second degree murder conviction according to prosecutors.
Trayers will spend her sentence at a facility in Los Angeles that specializes in mental health care as requested by the defense.
