A Long Island man with a history of alleged stalking behavior toward pop star Billie Eilish was struck and killed by a Long Island Rail Road train in Westbury last month, according to MTA Police Department officials and court records.
Prenell Rousseau, 30, of Farmingville, was on the tracks east of the Westbury LIRR station at approximately 5:38 a.m. on Wednesday, March 25, when he was hit by a passing train. An MTA Police Department spokesperson confirmed that Rousseau was pronounced dead at the scene and that no criminality is suspected in his death. No other injuries were reported.
The train, carrying roughly 100 passengers on its route from Huntington to Atlantic Terminal, was stopped following the incident. Those passengers were transferred to another train to complete their journey, according to the LIRR.
Rousseau had a documented legal history with Eilish stretching back to 2020. Court records from Los Angeles County Superior Court show that Eilish, who was 18 at the time, was first granted a temporary restraining order against Rousseau in May of that year. The order was subsequently extended for multiple years.
Court documents cited by a British newspaper detailed some of the behavior that led to the restraining order. Rousseau had allegedly appeared at Eilish’s home, where he was found reading a book on her porch while delivering a monologue, even as he was asked to leave the premises multiple times. The incidents painted a picture of persistent, unsettling behavior directed at the Grammy Award-winning artist.
Eilish, a 10-time Grammy winner, has spoken publicly in the past about the difficulties of navigating fame at a young age, including the unwanted attention that can come with it. She performed two shows at UBS Arena on Long Island in October 2025 as part of her concert tour.
Westbury and the surrounding communities in Nassau County are no strangers to the kinds of LIRR disruptions that incidents on the tracks can cause, and Wednesday morning’s events affected commuters headed into the city during the early morning rush. Service was restored after passengers were transferred.
The MTA Police Department continues to handle the investigation, though officials have indicated nothing points to foul play. The circumstances of how Rousseau came to be on the tracks remain part of the ongoing review.
The case brings renewed attention to the serious and sometimes dangerous nature of celebrity stalking. Restraining orders, while a critical legal tool, represent one layer of protection for public figures who find themselves targeted by obsessive individuals. For Eilish, the 2020 order came at a particularly vulnerable moment, just as she was emerging as one of the biggest names in pop music at a remarkably young age.
Rousseau’s death closes a chapter in a legal case that had stretched across several years and multiple court filings. For the roughly 100 commuters who found themselves sitting on a stopped train in the pre-dawn hours of a March morning, it was a jarring start to what might have otherwise been an ordinary Wednesday.
LIRR officials have not commented further beyond confirming the service disruption and the passenger transfer. The MTA Police Department spokesperson did not provide additional details beyond confirming the basic facts of the incident and that no criminality is suspected.
