Prosecutors say Pena snuck into his estranged wife's home on November 29, 2016, and used a buck knife to stab her to death.
The prosecution says he then scrubbed the scene with bleach and drove around with her body in the car before police tracked down the body and vehicle using pings from wife's cell phone.
The prosecution believes Pena was upset after his wife kicked him out of the house just 10 days prior to the murder.
Pena is facing 26 years to life in prison.
