A violent career criminal accused of murdering his twin sister in New Jersey last week was released on bail earlier this year after shooting a bystander in the back during a shootout in Manhattan.

Jonathan D. Hagley, 26, is in the psychiatric unit of the Bergen County Jail after police say he shot and killed his twin sister, Naomi Hagley, in his family home on Hickory Street in Teaneck on Thursday, according to jail records and the county prosecutor’s office.

It’s not clear what prompted the murder, but when police arrived at the quiet suburban home minutes from Manhattan, they found Naomi mortally wounded with three gunshot wounds — and the twins’ father said they came from Hagley’s gun.

Police arrested the suspected shooter a few blocks away – and found his pistol, a Glock 30S with a crossed-out serial number, in the same area.

But it wasn’t the first time Hagley – who now faces murder, weapons and obstruction charges for the killing – had run into trouble with the law.

According to the Bergen Record, Hagley shot a man in the back about eight months ago while chasing two other men during a shootout in Harlem.

The Jan. 15 altercation began near Hagley’s West 136th Street apartment complex when the unidentified couple approached him, shot him twice and then fled, Manhattan Assistant District Attorney Mary Rogowski said during Hagley’s sentencing hearing eight days later.

During the altercation, which was caught on camera, Hagley allegedly chased the men around the block and then fired three shots in the middle of a busy intersection in broad daylight, the Record reported.

One of these bullets hit a 37-year-old pedestrian in the spine as he stood near the median.

Authorities found three shell casings at the scene, Rogowski said. A handgun and an extended magazine were recovered on 7th Avenue, where Hagley weaved between cars and then strolled into a deli.

The shooter – who was on probation at the time due to previous convictions in the Garden State – was also hit in the butt by a bullet fired by his opponent and required medical attention himself, the Record said.

At his hearing in Manhattan Supreme Court on January 23, he pleaded not guilty to charges of attempted second-degree murder, assault and other crimes.

A judge ordered him released on bail of $100,000 or $300,000, but Hagley somehow came up with the money and was released, according to the Record.

Eight months later, his twin sister allegedly became his next victim.

Hagley, who is scheduled to appear in Manhattan court on Sept. 9, was also scheduled to appear before a Bergen County judge on Friday.

However, because he was sedated, his lawyer David Blum declined to appear at the hearing.

New Jersey prosecutors plan to keep Hagley in custody until the end of his trial, the Record said. He is scheduled to appear in court again next week.

The trigger-happy Hagley has often gotten into trouble.

In March 2018, he was sentenced to seven years in state prison after pleading guilty to aggravated assault, burglary and weapons possession for attempting to rob an apartment in Garfield, New Jersey, in 2016, according to the Record.

While awaiting trial in the Bergen County Jail, Hagley allegedly slashed another inmate in the face with a blade, leading to assault charges.

The long prison sentence was part of a comprehensive agreement that combined both crimes into one, the Record said.

Hagley fought against his conviction but lost all appeals.

As a result, he remained behind bars until November 2022, when he was released from Bayside State Prison.
