What Happened
Joshua Alvarado, a Queens man, was indicted on manslaughter and vehicular manslaughter charges following a fatal drugged-driving crash on Sunrise Highway in Merrick that killed a 70-year-old Nassau County Police crossing guard, Nassau County District Attorney Anne Donnelly announced on Tuesday, March 31, 2026.
On February 26, Alvarado was driving a commercial pickup truck eastbound on Sunrise Highway in Merrick while en route to a service call for an extermination business when he allegedly fell asleep at a red light at the intersection of Merrick Avenue and Sunrise Highway, according to Donnelly. After the light turned green, witnesses reported that the honking of fellow drivers startled Alvarado awake, and that he drove diagonally through the intersection, bearing left towards Merrick Avenue, mounted the curb, and struck 70-year-old John Miro, who was standing on the sidewalk, the DA said.
Miro, a Nassau County Police crossing guard, was clearing the sidewalk of snow and helping children cross the intersection moments before he was hit, Donnelly said. The 70-year-old suffered severe injuries from the impact, including blunt force trauma to his head, a broken hip, and multiple broken ribs, according to the DA. Miro was immediately transported to the hospital for emergency surgery but ultimately died from his injuries on March 6, eight days after the collision.
The investigation revealed that Alvarado was allegedly operating his vehicle under the influence of powerful sedatives and illegal street drugs at the time of the crash. A toxicology report confirmed that Alvarado was impaired by Xanax and Clonazepam when he struck Miro, Donnelly said. The blood results also revealed the presence of an illegal and highly potent synthetic drug known as “street Xanax,” according to the DA.
Alvarado was arraigned on multiple charges including manslaughter, vehicular manslaughter, assault, two counts of driving while ability impaired by drugs, and driving while ability impaired by the combined influence of drugs. He pleaded not guilty to all charges and is scheduled to return to court on May 5. If convicted on all charges, Alvarado faces up to seven to 15 years in prison, according to the Nassau DA’s office.
The tragic incident occurred during what appears to have been routine morning activities, with Miro performing his duties as a crossing guard by helping children safely navigate the busy intersection and clearing snow from walkways when he was fatally struck by Alvarado’s commercial vehicle.
Location & Road Context
The fatal collision occurred at the intersection of Sunrise Highway and Merrick Avenue in Merrick, one of Nassau County’s busier thoroughfares. Sunrise Highway, also known as Route 27, is a major east-west arterial road that runs through multiple Long Island communities and carries significant commercial and commuter traffic throughout the day.
The intersection where the crash took place is in a developed area of Merrick where pedestrian activity is common, particularly during school hours when crossing guards like Miro assist children in safely navigating the busy roadways. The presence of sidewalks and designated crossing areas indicates this is a pedestrian-friendly zone where drivers are expected to exercise heightened caution.
Investigation & Legal Proceedings
The comprehensive investigation into the February 26 crash included toxicology testing that revealed the extent of Alvarado’s impairment at the time of the collision. The Nassau County District Attorney’s office built their case around evidence showing Alvarado was under the influence of multiple substances, including both prescription medications Xanax and Clonazepam, as well as the illegal synthetic drug commonly referred to as “street Xanax.”
The multiple charges reflect the severity of the incident and Alvarado’s alleged impaired state. The manslaughter and vehicular manslaughter charges carry the most serious penalties, while the multiple drug impairment charges address the various substances found in his system. With Alvarado pleading not guilty at his arraignment, the case will proceed through the court system with his next appearance scheduled for May 5. The potential sentence of seven to 15 years in prison reflects the serious nature of the charges and New York State’s approach to prosecuting fatal crashes involving impaired driving.
Broader Impact
This case highlights the dangerous combination of prescription drug abuse and illegal synthetic substances behind the wheel, particularly involving “street Xanax,” which has become an increasing concern for law enforcement due to its unpredictable potency and effects. The death of John Miro, who was performing essential public safety duties as a crossing guard, underscores the vulnerability of pedestrians and public servants who work near busy roadways and depend on drivers to operate their vehicles responsibly and without impairment.
