ALBUQUERQUE, N.M. — Authorities have arrested two 18-year-olds for separate murders that occurred within the last year in Albuquerque.

New Mexico State Police on Tuesday arrested Juanito Montoya for the December murder of Adrian Vallejos in southwest Albuquerque. An officer pulled Montoya over for speeding on U.S. 285, near mile marker 105, near Roswell. They found he had an active warrant for murder and multiple other charges in Albuquerque.

Montoya faces charges of murder, conspiracy, robbery, aggravated assault with a deadly weapon and tampering with evidence.

According to APD, the shooting happened near Gibson and Snow Vista Boulevard in the southwest part of town. When officers arrived, they found Vallejos with a gunshot wound. He later died at the hospital.

Investigators say people were trying to break into Vallejos’ car. Vallejos realized what was happening and armed himself before going outside with his girlfriend to confront them. As he did, they shot Vallejos and took off in a white sedan.

Officers found a firearm near the scene. A review of ShotSpotter data, surveillance video and photos, and social media conversations linked Montoya to the murder, prompting police to issue the warrant last Wednesday.

Then on Wednesday, Albuquerque police arrested Angelo Andrade for the murder of Jeremiah Houston.

Police say Houston was shot at least 10 times in a parking lot on Copper and Sixth. Surveillance video showed at least two suspects fired shots. It also showed the suspects getting into a pickup Andrade owned before getting out when it didn’t start.

Police tracked down Andrade through surveillance video, executing a search warrant they obtained of a truck, and a review of social media and phone data. The phone data allegedly placed Andrade at the scene of the shooting.

Police obtained a warrant for Andrade’s arrest April 24. They tracked him to a home in the South Valley. SWAT officers then arrested him Wednesday.

Andrade faces charges of murder (depraved mind), felony murder with a firearm enhancement and tampering with evidence. He is now at MDC.
