BOSTON — A man who says Kevin Spacey groped him at a bar on a resort island cannot find the cellphone he has been ordered to turn over to the defense, the accuser's attorney said Wednesday.

Spacey's lawyers have demanded the phone so they can try to recover text messages they say would support Spacey's claims of innocence. The judge said earlier this month that the phone must be given to authorities by Friday.

But the accuser's attorney, Mitchell Garabedian, told the judge in court documents that the phone used by the man at the time of the alleged groping at a Nantucket bar is missing.

The young man and his parents "have searched all the places where such a phone may have been stored. They have not found the phone," Garabedian said.

The judge is now giving them until July 8 to produce the phone or the man, his mother and Garabedian must appear in court that day to explain what they know about its whereabouts.

The phone has been a central issue in the case against Spacey, who pleaded not guilty in January to a charge of indecent assault and battery.

The case first came to light in 2017, when former Boston TV anchor Heather Unruh said Spacey got her then 18-year-old son drunk and then sexually assaulted him at the Club Car, a popular bar and restaurant on the resort island.

It's the only criminal case that has been brought against Spacey since several sexual misconduct allegations crippled his career in 2017.

Spacey's attorney, Alan Jackson, said at a hearing this month that Unruh told authorities she removed anything concerning her son's "frat boy activities" from his phone before handing it over to investigators in 2017.

Jackson has said it also appears the accuser deleted certain messages between him and his then-girlfriend from his phone before sending screenshots of conversations to an officer investigating the case.

Jackson didn't immediately respond to a phone message on Wednesday. An email was sent to a spokeswoman for the Cape & Islands District Attorney's Office, but was not returned.

Garabedian said Spacey's accuser and his parents have no memory of seeing the phone since it was given to authorities back in 2017. Officials have indicated that the phone was returned to the man's father, but his father doesn't remember getting the phone back from police, the lawyer said.

Garabedian said they are using an expert to search for backup copies of the phone but understand "it will take a few weeks to identify that information."
