Daniel Penny — the former Marine who put homeless man Jordan Neely in a deadly chokehold on the subway last week — is expected to surrender to face criminal charges, law enforcement sources with knowledge of the case said Thursday.

It wasn’t immediately clear what charges Penny, 24, faces or when exactly he would turn himself in.

The Manhattan District Attorney’s Office had been investigating the May 1 encounter that left Neely, a 30-year-old homeless man with a long history of mental illness, unconscious on the floor of an F train.

He died at a hospital in what the city’s medical examiner ruled a homicide.

Penny was questioned by cops in the aftermath and then released without charges.

His attorneys have said he didn’t intend to kill Neely when he put him in the chokehold. The lawyers didn’t immediately return a call and email for comment.
