JERUSALEM (JTA) — Yigal Amir, who assassinated Prime Minister Yitzhak Rabin in 1995, filed a request for a retrial.

The request was filed with Israel’s Supreme Court on Sunday, after Amir met with his attorney, Gabi Shachar, in prison. During the meeting Amir reportedly signed the documents necessary to request the retrial, Hadashot news reported.

Amir, 47, was sentenced to life in solitary confinement in prison for the murder, which occurred after a peace rally in Tel Aviv. Amir confessed to shooting Rabin and reenacted it for police. He opposed Rabin’s territorial concessions, a condition of the Oslo Accords, which Rabin signed with then-Palestine Liberation Organization leader Yasser Arafat.

Amir’s wife, Larissa Trimbobler, whom he married in a proxy ceremony while in prison, in a Facebook post a week ago said that Amir would seek a retrial and in a second post a day later wrote that Amir’s defense lawyers have evidence that the bullets he fired at Rabin did not cause his death.

Amir’s lawyer on Sunday would not say whether he would present new evidence, according to Hadashot news. “At this stage I’m not going to detail the evidence,” he said.
