POST FALLS - A Spokane man has confessed to slipping a phone under a changing room door at the Post Falls Walmart with a mother and daughter inside, according to police.

Mikhail Marshalkin, 33, faces a pending felony video voyeurism charge for the Feb. 7 incident involving a mom and her 10-year-old daughter at the Walmart on Mullan Avenue. The pending charge will likely result in an arrest.

Post Falls Police Detective Mark Goodwin said it's unclear whether Marshalkin captured video of either of the females undressing or failed in his attempt.

"We could not find any evidence of a video," said Goodwin, adding that Marshalkin and a translator responded to the Post Falls police station when asked to come in for an interview. "We searched his phone and nothing was located. He said that he doesn't keep any of the videos he gets. He said he doesn't transmit them and just deletes them."

Marshalkin was also charged with the same crime in 2012 at NorthTown Mall in Spokane.

A loss-prevention employee at a retailer in Spokane who was familiar with that earlier case linked police to the Post Falls case, Goodwin said.

When police responded to Marshalkin's home in Spokane, they identified the suspect's distinctive newer black truck with suspension lift, which had been caught on Walmart surveillance video.

"We then requested that he come to the police department for an interview and he was very cooperative," Goodwin said. "During the interview, he admitted to being involved."

The mother told police that she and her daughter were in the changing room about 7 minutes when she noticed the phone.

"She did not see any hands, just the phone," the police report states. "She yelled to get the phone out and the person left. (The mother) did not see the suspect at any time."

The surveillance video showed the suspect leaving the store via the west exit and running to the far north end of the parking lot to Mullan Avenue. He then walked east toward Chase Bank and back south near Walmart's garden center where his truck was parked. The truck exited onto Cecil Road.

Goodwin said photos of the suspect's truck and his profile posted by news outlets and social media generated a lot of tips.

"We appreciate all of the tips that people supplied us with," he said.
