KENNEWICK — A 26-year-old man was found guilty Friday of killing his 18-year-old girlfriend and her toddler in Southeastern Washington.

The Tri-City Herald reported that Prudencio Juan Fragos-Ramirez was convicted of two counts of first-degree aggravated murder.

Fragos-Ramirez was accused of shooting Maria Cruz-Calvillo in July 2015 because he was possessive and obsessed with her.

Authorities said Cruz-Calvillo and her 3-year-old son, Luis Lopez-Cruz, were shot inside a car, which was then set on fire.

The burning vehicle was found in a ravine in northern Franklin County.

Attorney Scott Johnson argued that the mother and son likely were killed by drug dealers.

Fragos-Ramirez faces life in prison without the possibility of early release or parole.
