UPDATE, 2:30 p.m. Monday: At a 2 p.m. news conference, New Orleans police said that Euric Cain has confessed to shooting Tulane Medical School student Peter Gold.

Cain was arrested Monday morning at an Uptown home.

Police also said they have arrested Cain's 17-year-old girlfriend, Nictoria Washington, and booked her as an accessory after the fact to attempted murder.

Washington allegedly helped harbor Cain. It is not clear if police believe her involvement is any greater than that.

UPDATE, noon Monday: The suspect in Friday's shooting of Tulane Medical School student Peter Gold was arrested Monday, officials said.

The New Orleans Police Department and U.S. Marshals Service arrested Euric Cain, 21, at a home in the 2200 block of Delechaise Street around 11:30 a.m., NOPD spokesman Tyler Gamble said in a news release.

More information will be provided at a 2 p.m. press conference.

Original story:

A suspect has been identified in Friday’s shooting of “good Samaritan” Tulane Medical School student Peter Gold, New Orleans officials said Sunday.

Gold was shot trying to rescue a woman from an apparent abduction in the 1000 block of St. Mary Street, just off Magazine Street.

Euric Cain, 21, is wanted in connection with the crime, Police Superintendent Michael Harrison said Sunday afternoon.

Police said they identified Cain after his SUV was found Sunday morning in the 2200 block of John Raphael Place.

At a news conference held at police headquarters, Mayor Mitch Landrieu urged the public to help police find the suspect.

A $12,500 reward is being offered for information leading to the apprehension of Cain. Police said he is wanted on counts of attempted first-degree murder, second-degree kidnapping and armed robbery.

“We know who you are, and you need to know we are going to find you,” Landrieu said about Cain. “We need the public’s help to do this, but there is no question, now that we know who he is, that he will be brought to justice. And anyone who harbors him is going to be arrested and convicted to the full extent of the law.”

Police said Cain shot Gold after the fourth-year student at Tulane Medical School tried to stop the apparent abduction. Chilling video shows Cain trying repeatedly to shoot Gold in the head, but the gun malfunctioned each time. He managed to shoot Gold in the stomach instead.

Gold was driving on Magazine Street about 4 a.m. Friday when he spotted a woman being carried against her will to a nearby car on St. Mary Street. As the woman crumpled to the sidewalk, Gold backed up and turned against traffic on St. Mary, rushing to her aid.

As he crouched at her side, the man who had been carrying her jumped out of a sport utility vehicle with a semi-automatic weapon and pointed it at Gold’s face, demanding money. When Gold said he did not have any, police said, the man became enraged and shot Gold in the stomach and tried to shoot him several more times, but the gun jammed each time. Afterward, the shooter took the woman’s purse and drove away.

The video footage, captured by a private security camera positioned overhead, was turned over Friday morning to the Police Department.

On Sunday morning, members of the NOPD Special Operations Division recovered the SUV seen in the video, Harrison said.

From there, “very smart and aggressive police work” led them to identify Cain as the suspect “responsible for this heinous crime,” he added.

Landrieu said New Orleans police, State Police and U.S. marshals are “going to work around the clock” until they find Cain.

The widely viewed video of the attempted execution sent fresh shock waves through Uptown neighborhoods already shaken by several brazen armed robberies in recent months.

At the news conference, Harrison credited the high-resolution video for the quick identification of the suspect.

Gold, who remains in guarded condition at University Medical Center, continues to improve, police said.

The woman who was being abducted has been cooperative but did not know her abductor, police said. After the incident, she was treated for minor injuries and released.

“Mr. Cain will spend the rest of his life in jail,” Landrieu said. “This kind of brazen violence in our city is not going to stand. We’ve said enough is enough.”

Cain was last arrested Nov. 2 for possession of a stolen cellphone that was taken in a carjacking in the 1st District. His previous criminal history includes arrests for possession of a stolen vehicle and various weapons charges, Harrison said.

“It is clear that this is a dangerous individual who doesn’t value the lives of others,” Harrison said, urging New Orleanians to “take a good look” at Cain’s photo and help identify him.

“Someone knows who he is,” Harrison added. “Someone knows where he is hiding.”

Sixth District Commander Ronnie Stevens said he had “full confidence” that Cain would be found.

“There’s only so far you can go to run and hide with the U.S. marshals and federal, state and local officials out there,” Stevens said.
