RITZVILLE, Wash. (AP) _ A Chicago man will be sentenced to 30 years in prison for murdering his girlfriend on Interstate 90 in front of their 3-year-old son.

The Columbia Basin Herald reported Thursday (http://bit.ly/2jmQq7Y ) that 34-year-old Manuel Argomaniz-Camargo was sentenced after previously pleading guilty to first-degree murder and possession of methamphetamine.

Argomaniz-Camargo admitted to bludgeoning Ana Montelongo Garcia with a hammer and stabbed her with a screwdriver on I-90 near Ritzville in March 2015.

According to court documents, Argomaniz-Camargo, Garcia and their young son left the Chicago area on a cross-country trip to Washington. Argomaniz-Camargo admitted to investigators that he ingested meth and cocaine to help him stay awake to drive. When they were near Ritzville, Argomaniz-Camargo forced Garcia out of the car, accused her of doing witchcraft to their car and struck her with a hammer.
