NEW PORT RICHEY, Fla. -- Convicted killer Adam Matos' life hangs in the balance as he will try to convince jurors to spare his life.
The jury found Matos guilty on four counts of Premeditated First-Degree Murder on Thursday in the 2014 slaying of his ex-girlfriend, her parents and her new boyfriend.

During the trial, Matos admitted to killing Megan Brown, Greg Brown, Margaret Brown and Nick Leonard but claimed that self-defense and "paranoia" led to the brutal quadruple-homicide.
Prosecutors say he carefully planned the murders because he was enraged after finding out the mother of his child, Megan Brown, had a new man in her life.

During the sentencing phase of the trial, jurors have only two options: life in prison without the possibility of parole, or a death sentence.
Prosecutors say they plan to seek the death penalty against Matos.
If the jury recommends capital punishment, the jury must make a unanimous decision.
“Either way his life is over. That’s basically all we can really ask for. Keep him off the streets,” said Daniel Leonard, father of victim Nick Leonard.
The defense plans to call up 15 character witnesses to the stand during the sentencing phase, including family members, in hopes of persuading jurors to spare Matos' life.
The penalty phase of the trial will begin on Monday at 9:30 a.m.
