Miami police arrest driver accused of fatal Little Havana scooter hit-and-run after victim died days later

Arrest follows late-December crash and delayed death

A Miami man has been arrested in connection with a Little Havana crash involving a standup electric scooter rider who later died from his injuries. The case centers on a collision that occurred on the night of Dec. 30, 2025, at the intersection of Southwest 14th Avenue and Southwest 6th Street, and an arrest completed the following month after investigators tied a rented SUV to the crash.

Police allege the driver failed to stop at a stop sign before striking the scooter rider, then left the scene without providing aid. The rider was taken to Jackson Memorial Hospital’s Ryder Trauma Center in critical condition and died on Jan. 7, 2026, after being treated for a traumatic brain injury, fractured ribs and a liver injury.

Traffic stop the next day helped investigators identify the vehicle

Investigators located the suspected driver on Dec. 31, 2025, during a traffic stop in the same general area. Police reported that an officer observed the SUV traveling the wrong way near Southwest 7th Street and 17th Avenue and stopped it. The vehicle showed damage described as consistent with a collision involving a person, including front-end damage, a missing front left quarter panel and windshield damage.

Police said the driver was identified using a Guatemalan passport and was taken to the Miami Police Department for an interview, where he admitted being behind the wheel when the SUV struck the scooter rider the previous night. Investigators said he returned to the station on Tuesday and was taken into custody.

Charges filed and detention at TGK

The defendant, identified by police as Javier Sanjay-Tzay, 27, faces two felony allegations: leaving the scene of a crash resulting in death and driving without a valid license causing death. Court proceedings also referenced an immigration hold.

As of Wednesday morning following the arrest, he was being held at the Turner Guilford Knight Correctional Center. Jail records listed bond as “to be set.”

What remains unresolved

• The scooter rider’s identity has not been publicly released in the available case summaries.
• The timeline indicates the death occurred days after the crash, a factor that can shape investigative documentation and charging decisions.
• No public information in the available reports indicates impairment allegations; the case as presented is focused on right-of-way, failure to stop, and leaving the scene.

The case is expected to proceed through bond proceedings and subsequent court hearings as prosecutors pursue the charged counts and defense counsel responds to the allegations.
