A convicted murderer, accused of stalking his soon-to-be ex-wife, was released on house arrest in Roswell, after he agreed to waive a preliminary hearing.
Prosecutor Kent Wahlquist withdrew his motion on March 24, to have Javier Alonzo, 46, of Santa Cruz, held without bail pending trial after Alonso waived a preliminary hearing in exchange for prosecutors agreeing to house arrest.
Alonzo agreed to the deal the same day the case was set for a pre-trial detention and preliminary hearing on charges of aggravated stalking, battery, felon in possession of a firearm and two counts of aggravated assault with a deadly weapon.
Those are slightly different charges than those that New Mexico State Police Officer Noberto Medrano-Tapia sought an arrest warrant for on Feb. 5. That arrest warrant charged Alonzo with aggravated assault, felon in possession of a firearm, violation of a protection order and harassment. He arrested Alonzo on Feb. 11, six days later.
Wahlquist initially sought to have Alonzo held without bail on Feb. 12, citing a previous murder conviction.
Alonzo allegedly repeatedly violated a no contact order by contacting his wife, who filed for divorce in October 2025. He allegedly emailed her, sent her communications through CashApp, tried to get her phone number from her landlord, called her children’s phones and had his mother go to her house, Medrano-Tapia wrote.
The woman told police that Alonzo brandished a gun inside a car, cocked it, placed it to her head and threatened to kill her. Police cruisers were nearby so he threatened to kill her before she could reach safety, he wrote.
In another incident in a Walmart parking lot, Alonzo allegedly punched out a vehicle windshield and restrained her while she tried to call for police. Bystanders intervened, Medrano-Tapia wrote.
She provided videos to the officer, showing Alonzo holding a gun and threatening her, he wrote.
Murder Conviction
Court dockets show Alonzo pleaded guilty to second degree murder in 2004 for an incident in Roswell, and received the maximum sentence, 15 years, followed by two years of probation.
His ex-wife told State Police officers that he killed a man while in prison, Medrano-Tapia wrote.
While Alonzo is not on probation in New Mexico, he is being supervised following his release in a federal case where he pleaded guilty to “violent crimes in aid of racketeering (murder).” He was sentenced to four years and three months, starting on Sept. 30, 2022, followed by supervised release for five years.
When federal prosecutors charged him in late 2015, the United States Attorney’s Office in New Mexico wrote in a press release, that he was one of 25 alleged gang members charged in connection with four killings under an initiative to prosecute the “worst of the worst,” who are members of the Syndicato de Nuevo Mexico, a New Mexican prison gang. The charge he pleaded guilty to was for his involvement in the killing of a person in 2007, “in aid of the Gang’s racketeering affairs,” according to 2015 the press release.
