ROCHESTER, N.Y. — ​New York State Attorney General Letitia James released the full grand jury transcript Friday afternoon about the investigation into the March 2020 death of Daniel Prude while he was in police custody.

This report has been weeks in the making since the grand jury made its decision not to indict officers involved in the arrest on February 23.

Prude was visiting his family in Rochester, but later died in police custody after several mental hygiene calls. The medical examiner's office ruled it a homicide.

Spectrum News has examined hundreds of pages of transcripts from the massive report the attorney general released Friday. The transcript gives a broad picture of what took place weeks before Prude came to Rochester, and what transpired once he arrived in March.

The grand jury proceedings were conducted in secret with more than nine days of testimony starting in October 2020 and ending in February 2021. Prude’s brother, along with police officers, EMTs and other experts were called in as witnesses in the case.

The first witness was Daniel Prude's brother, Joe Prude. He talked about a recent visit in February where he described Daniel as “happy,” as they played basketball, grilled and competed like kids.

Things changed when Prude went back to Chicago, where his sister later suspected he was on drugs. Fast forward a few weeks later to the Buffalo area, where Daniel Prude was kicked off a train and taken to a shelter. Police in Cheektowaga say Prude was non-violent and seemed confused as he was trying to make it to Rochester.

Joe Prude said when he picked him up from the shelter, “He didn't look like my brother that left me the first time,” a reference to his brother’s visit a few weeks earlier in February.

His brother instantly knew something was different and later called 911 for the first time hours after they made it back to Rochester.

Other witnesses called included the 911 operator who took the first call, and the first responding officers who took Prude to Strong Hospital, where he was later discharged.

Daniel Prude is described as being normal when he returned back to his brother's house, but things changed hours later when he ran away from his brother’s house and encountered police on Jefferson Avenue. Paramedics believed Prude was experiencing excited delirium.

Many of the questions on the fifth day of testimony involved medical experts called in with knowledge of restraint-related deaths. The expert said when it comes to excited delirium, the best treatment was restraint and a sedative.

The expert said not all people experiencing excited delirium die in restraint, and added the spit hood did not cause cardiac arrest or lead to Prude's death. The expert believes the video did not show police holds that would restrict breathing.

The Office of the Attorney General presented the charge of criminal negligent homicide to the grand jury because it believed the three officers’ restraint of Daniel Prude caused his death.

In the end, the grand jury voted 15-5 not to charge the three Rochester police officers with one charge of criminally negligent homicide.
