What Happened
Miandad Khan, 38, of Dix Hills pleaded guilty Friday to aggravated vehicular assault and four additional charges stemming from a three-crash sequence he caused on Deer Park Avenue on May 17, 2025, that injured five people, the Suffolk County District Attorney’s Office announced. Khan admitted in court that he was impaired by marijuana when the crashes occurred, according to Patch.
Khan was driving a 2016 Mercedes-Benz E350 north on Deer Park Avenue at about 3:20 p.m. when he struck a 2020 Acura near Jacqueline Way, prosecutors said. Rather than stop, he accelerated over a landscaped center median and entered the southbound lanes while still heading north, in an attempt to flee the scene. He was now driving the wrong way against oncoming traffic on a multi-lane commercial corridor.
Continuing north in the southbound lanes, Khan struck a Honda SUV carrying two teenagers, spinning the vehicle out, according to prosecutors. He kept going through the intersection at Grand Boulevard before slamming head-on into a Toyota RAV4 occupied by a couple in their 70s. The force of that collision pushed both the RAV4 and Khan’s Mercedes into other vehicles stopped at the traffic light.
The two occupants of the RAV4 had to be extricated by emergency responders and were transported to Good Samaritan Hospital, where they underwent surgery for facial and spinal fractures, the Suffolk County DA’s Office said. The two teenagers in the Honda were also taken to the hospital and treated for minor injuries. The driver of the Acura, the first vehicle Khan struck, received medical treatment for her injuries. Five people in total were hurt across the three-vehicle chain.
An investigation after the crash determined Khan was impaired by marijuana at the time of the incident, prosecutors said. News 12 Long Island reported the case as a multivehicle wrong-way pile-up. Khan’s guilty plea came more than 15 months after the May 2025 crash.
“This defendant drove while impaired, hit another vehicle, then tried to flee the scene by speeding into oncoming traffic — causing a second collision and then a third, leaving behind multiple injured victims and wrecked vehicles,” Suffolk County District Attorney Ray Tierney said in a statement released Friday.
Khan pleaded guilty before Supreme Court Justice John B. Collins to aggravated vehicular assault, two counts of second-degree assault, driving while ability impaired by drugs, and third-degree assault. His attorney, William Keahon, was not available for comment, according to Patch.
Location & Road Context
Deer Park Avenue runs north-south through Deer Park and carries heavy commercial and residential traffic between the Deer Park business corridor and neighborhoods north toward Dix Hills. The stretch near Jacqueline Way and Grand Boulevard includes a landscaped center median that divides northbound and southbound lanes. Khan crossed that median after the initial collision, putting him directly in the path of southbound traffic for several blocks.
The crash site on Deer Park Avenue near Grand Boulevard sits roughly two miles north of the Deer Park LIRR station and is a signalized corridor with regular stop-light sequencing — the vehicles Khan’s Mercedes ultimately forced into at the Grand Boulevard light were stopped lawfully at red.
Investigation & Legal Proceedings
Khan entered his guilty plea August 28, 2026, before Supreme Court Justice John B. Collins in Suffolk County, the DA’s Office confirmed. He faces two to six years in state prison. His next court date is October 30, 2026, when sentencing is scheduled.
The five charges Khan admitted to carry different sentencing exposures. Aggravated vehicular assault, a class C felony under New York Penal Law § 120.04-a, is the most serious count and drives the two-to-six-year prison range prosecutors cited. The drug-impairment finding underlying the charges corresponds to a violation of VTL § 1192.4 (driving while ability impaired by drugs). Khan is represented by attorney William Keahon.
Broader Impact
Deer Park has seen two high-profile impaired-driving cases reach the sentencing stage in August 2026 alone. Two weeks before Khan’s plea, a driver convicted in a deadly Deer Park nail salon crash appeared before a judge on August 12. Under New York Penal Law, a class C felony conviction for aggravated vehicular assault carries a maximum of 15 years, though prosecutors here are recommending the two-to-six-year range as part of the plea agreement.
