A man accused of stealing from the Maricopa County Election Department is now accused of stealing vintage jewelry from the Phoenix Art Museum.

The latest charges filed Monday mean 27-year-old Walter Lingfield Jr. has been accused of theft or burglary four times in the past two years.

Lingfield already is accused of stealing voting equipment keys from the Maricopa County Elections Headquarters on June 20 while working as a temporary elections worker.

The Maricopa County Attorney's Office filed two new charges against Lingfield on Monday, one of which is related to a previously reported incident at the Arizona Senate. According to court records, Lingfield was charged with felony theft and misdemeanor trespassing for allegedly stealing a challenge coin and other “desk accessories” from the desk of a Senate security officer.

In the second new case, the Maricopa County Prosecutor's Office said Lingfield is guilty of theft for allegedly stealing $9,500 worth of vintage jewelry from the Phoenix Art Museum on May 20. According to court documents, Lingfield entered the museum during a private event and made off with jewelry that was attached to several mannequins in an exhibit at the Orm Lewis Gallery.

Although the theft was captured on the museum's security cameras, Phoenix police did not link Lingfield to the incident until June 27, when Fox News ran a story about the theft at the Maricopa County Election Department that included Lingfield's photo.

“Phoenix Police Department investigative analysts recognized the suspect as the same individual who appeared in a bulletin distributed in connection with this investigation,” according to the police report.

According to Phoenix Police, the suspect left the museum in a gray sedan matching the description of a vehicle registered to Lingfield. Footage provided to Phoenix Police by the Arizona Department of Public Safety also showed the suspect wearing what appeared to be an “Elgin American utility pocket watch stolen from the Phoenix Art Museum.”

All five stolen items were recovered in good condition Tuesday, museum spokeswoman Samantha Andreacchi said.

The fourth incident dates back to 2023, when authorities say Lingfield stole more than $1,000 from a Fry's grocery store. Lingfield was arrested in that case, but because he participated in a diversion program, the theft did not come up in a background check conducted before he was hired as a temporary election worker, Maricopa County election officials said.

Prosecution in that case has been stayed, but the diversion agreement is now “void,” according to Maricopa County Attorney's Office spokeswoman Janine Lecuyer, who added that county attorneys have filed a motion to resume prosecution of the case in 2023.

“When someone fails to convert, we basically say, 'OK, that's enough, we're going to prosecute now.' … He clearly likes to steal things or is trying to steal things,” Lecuyer said.
