The US Marshals have offered an award for new information regarding the suspect involved in the shooting of Lady Gaga’s dog walker.

Last year, Ryan Fischer was attacked by three assailants attempting to kidnap Gaga’s three french-bull dogs – Koji, Asia and Gustav.

During the late-night scuffle, the 30-year-old suffered from a gunshot wound, which pierced his lung and resulted in numerous broken ribs.

Two months after the encounter, authorities arrested James Howard Jackson (18), Jaylin White (19), and Lafayette Whaley (27) in connection to the shooting.

However on 6 April, the Los Angeles County Sherriff’s department revealed that Jackson was mistakenly released from jail “due to a clerical error.”

Shortly after Jackson’s release, Fischer took to social media and urged the suspect to turn himself in.

“While I’m deeply concerned at the events that led to his release, I’m confident law enforcement will rectify the error,” he said.

“I ask for Mr. Jackson to turn himself over to the authorities, so resolution to the crime committed against me runs its course, whatever the courts determine that outcome to be. Thank you to everyone who is supporting me during this time.”

With Jackson’s location still unknown, the LASD Major Crimes Bureau have called on the US Marshal Service to assist with the investigation.

On 18 July, the federal law enforcement agency announced a cash reward for anyone with new leads regarding Jackson’s location.

“The Los Angeles Sheriff’s Department Major Crime Team has requested the US Marshals Service’s assistance to find and arrest Jackson,” they wrote via a press release.

“Jackson should be considered armed and dangerous. Anyone with information as to his whereabouts should contact law enforcement immediately.”

The recent development comes a few months after Fischer’s emotional grand jury testimony was released via Rolling Stone.

In the October transcript, he shared further details regarding his traumatic experience.

“The dog screamed at me, and I reached for him, and then the guy, the man with the gun, shot me as I was reaching,” Fischer recalled.

He went on to say that after he was shot, he fell to the floor before witnessing two of the three dogs being taken away in a Nissan Sentra.

“I immediately tried to call for help but realised I was bleeding out of my lung and that I was losing more and more air quickly,” he told the court,” he continued.

Towards the end of his testimony, Fischer told the judge that the violent incident severely damaged his lung – which ended up affecting his ability to stand.
