New York City’s mayor has urged people not to rush to judgment in the chokehold death of Jordan Neely, but five days after Neely was killed on the subway, authorities still have not provided several important details about the circumstances surrounding his death.

How long did Daniel Penny, a 24-year-old Marine veteran, place Neely in a chokehold? Who else was involved? And what happened leading up to the fatal encounter? The New York Police Department didn’t offer any updates when asked by USA TODAY for more details about the investigation on Saturday.

Neely was a 30-year-old locally-known Michael Jackson impersonator who died Monday in what a medical examiner ruled was homicide by compression of the neck.

In a Friday statement, Penny’s lawyers claimed he acted in self-defense. Advocates, family and Penny’s lawyers have all acknowledged Neely experienced mental illness.

Neely’s death sparked widespread protests in the city, as demonstrators demanded Penny be criminally charged, and prompted renewed conversations about mental health access, systemic racism and the treatment of New York City’s unhoused population.

Police silent on key questions

On Wednesday, police issued a statement saying they responded to the subway and discovered a 30-year-old man unconscious, who was later pronounced dead. A spokesperson told USA TODAY at the time the man had been in a “verbal dispute” with a 24-year-old that escalated to a “physical altercation.” The victim became unconscious during the altercation, the spokesperson said. 

By Saturday, NYPD had added few details to its public statement. Police said Neely was found unconscious on the floor of the train with other people standing at the scene. They added that responders performed CPR and said the medical examiner ruled the death a homicide.

Police also withheld Penny’s name for several days. Penny’s lawyers later released a statement on his behalf Friday amid building pressure on social media and from advocates for his identity to become public.
