TAMPA (FOX 13) - She told police she prayed with her in-laws. Then pulled out a gun and shot them both dead.
Marisol Best was in court Monday, facing two counts of first degree murder.
In November, investigators say Best shot and killed her mother- and father in-law, Virgil and Shirley Best, during a prayer session.
Marisol Best told police she was angry at them when they criticized their son and her husband, Robert Best after he was charged with performing sex acts with an underage girl in Polk County.
She told investigators she went to her car, grabbed a gun, then went to the bathroom and decided, "it's either them or me."
She then joined them in the living room for a prayer and that's when she pulled out a gun and shot and killed them.
Hillsborough state prosecutors considered her actions so heinous and depraved, they announced in court Monday, they will seek the death penalty in this case.
Best has pleaded not guilty to the charges. She is back in court in April.
