Lawyer on trial for strangling girlfriend ‘has killed before’

The lawyer on trial for strangling his girlfriend had killed before — when he was just 14 — a shrink testifying in his defense told a shocked Queens jury Thursday.

When Jason Bohn was in foster care 21 years ago, he punched a pregnant 18-year-old in the stomach, causing her to miscarry, Dr. Alexander Sasha Bardey testified.

The young Bohn “blacked out” afterwards and had no recollection of his action, Bardey said.

The shrink said it was the first blackout in a series that’s continued to the present — and diagnosed him with “intermittent explosive disorder.”

No charges were brought in the first killing — Bohn was already under psychiatric care and authorities made certain that the care was continued.

Bohn, 35, who got his undergrad degree at Columbia University, has conceded that he beat and strangled Danielle Thomas inside their Astoria apartment on June 24, 2012.

But he insists he has no memory of what happened.

Bardey blames Bohn’s memory loss on his “IED” and says because of it, he’s not legally responsible for the death of his gal pal, who was a 27-year-old Weight Watchers exec.

His medical condition, his shrink said, is a result of being abandoned by his mother, abused by his father and thrown into foster care.

“It can be very skeptical when an individual says they don’t remember; you have to look at the history of the patient or reasons for the suspected blacking out,” said Bardey.

In 1994, the doctor said, Bohn left foster care and was soon attacked by a group of teens.

He blacked out and was awakened by an officer at the Hartsdale Metro-North train station.

He was taken to a hospital in Yonkers but couldn’t remember any details about the attack, according to Bardey.

Bohn left a voicemail message for his ex-girlfriend, Jasmine Nieves, after he killed Thomas saying, “Ah, I don’t remember anything that happened, OK. I think I pushed her.” That recording was previously played in court.

In several messages left at the crime scene Bohn wrote, “When I woke up again, she was unconscious.

Bardey claimed, “in the mist of the IED, he functioned under extreme emotional distress, and as soon as he was out of the explosion he became rational again with his post-killing behavior.”

Bardey said a prosecution doctor who evaluated Bohn agreed with his diagnosis.
