Some high-profile celebrities are demanding answers after a 24-year-old died in prison in the Hudson Valley.

Anthony Myrie, 24, died unexpectedly on February 11 at the Greene Correctional Facility. He was serving a 7-year prison sentence for attempted sale of a controlled substance. He died 3-months into his seven-year sentence, WPIX reports.

“He seemed worrisome like he didn’t want to get off the phone and I kind of tried to pry to see what was wrong,” his wife told PIX11.

A spokesperson for the New York State Department of Corrections and Community Supervision said it appears Myries died from sudden cardiac arrested after three-on-one fight with other inmates.

“Mr. Myrie was involved in a 3 on 1 fight with other incarcerated individuals in a housing unit of the Greene Correctional Facility. Correction officers responded and issued verbal commands which stopped the fight," Thomas Mailey said in a statement obtained by News 10. No officers used any force at anytime. Following the altercation, Mr. Myrie was examined by faculty medical staff who found no injuries as a result of the incident.

Shortly after, Myrie complained of chest pain and was reexamined, according to Mailey.

"Myrie was immediately returned to the medical unit for further evaluation when he collapsed unconscious and unresponsive. At that point, medical staff began emergency response and called for outside medical services," Mailey said.

Myrie's death has gained national attention. Rappers Cardi B and Meek Mill have released comments accusing the Greene Correctional Facility of inmate abuse.

On Monday,  protesters were outside the Greene County prison demanding answers and justice for Myrie. Many protesters believe Myrie's death was caused by one or more prison guards, News 10 reports.
