A judge presiding over the case of a New York City doctor who died of a cocaine overdose has released surveillance video of the night a New York City dermatologist the mother of three lost her life while partying with an HBO producer.

As CrimeOnline previously reported, Dr. Kiersten Cerveny died in October 2015 after an early-morning cocaine overdose at the Manhattan apartment of a known drug dealer. The drug dealer, James Holder, and the producer, Marc Henry Johnson, dragged the woman’s body into the building’s vestibule and made an anonymous 911 call. Johnson was sentenced to a year in prison after pleading guilty to accessory after the fact to a narcotics offense.

Holder had previously been sentenced to five years in prison.

The Daily Mail obtained the minute-long surveillance video, showing footage taken right after Ceverny and Johnson arrived to the drug dealer’s apartment building, and hours later when paramedics arrive.

The video shows Johnson walking out of the building past the paramedic without acknowledging him.

When he pleaded guilty in court, Johnson tried to explain his actions.

“I was scared, frightened and panicked,” Johnson reportedly told the judge.

The dermatologist was by all accounts a happily married mother of three who lived on Long Island with her family.
