ALBUQUERQUE, N.M. — A man accused of killing his girlfriend Friday night is set to appear before a judge Tuesday.

Robert Mentz, 29, was supposed to make a court appearance Monday, but it was rescheduled due to medical reasons.


Mentz is charged with vehicular homicide and leaving the scene of an accident after allegedly killing his girlfriend, Brandi Garcia, with his car.

According to court documents, Garcia’s dad drove to a southeast Albuquerque neighborhood to pick up Garcia and her kids because she and Mentz were fighting.

Garcia’s dad said they all got into a verbal argument when he arrived, then he threatened Mentz with a stun gun. That’s when Mentz pulled out a knife.

Garcia’s dad was able to get his daughter and her kids in his van then drove off. Mentz subsequently crashed head-on into the van down the street. Afterwards, Garcia and her dad jumped onto the running boards of Mentz’s vehicle as he drove away. Garcia then fell off the side of the car and was killed.

According to the criminal complaint, Mentz denied intentionally running over his girlfriend and said “…he thought Brandi died from hitting her head after he slammed the brakes on and she fell off his vehicle.”

The documents also revealed that Mentz and Garcia had been dating for about a year and had been fighting a lot over the last two months.
