Kent County Prosecutor Chris Becker announced on Tuesday that his office has charged Andrew Hudson with one count of perjury in and investigative subpoena in 35-year-old Ana Carrillo's case. Becker said this is a felony punishable by life in prison.

Becker did not say what new details warranted this charge and did not have arraignment information. Hudson was charged with a misdemeanor for lying to police in the investigation.

On Monday, Sept. 11, Wyoming Police announced they suspect foul play and have begun investigating Carrillo's case a possible kidnapping and homicide -- naming Hudson as a suspect in her disappearance. He is one of the last people to have spoken to Carrillo before she went missing on Sept. 3.

Carrillo's family said that she had set out to pick up her children from Hudson's home, but never made it. Police found her car in a parking lot in Wyoming, less than a mile from his home, but she was nowhere to be found.

Tuesday friends and family of Carrillo held a search in Newaygo County. The group centered efforts around property they say at one time belonged to Hudson's grandparents. The area is along North Walnut Avenue in Wilcox Township.

Members of the search party also spent two hours looking along a Manistee National Forest trail. It's a location they believe Hudson knows well.

"Andrew has a connection, and we know Anna came here a few times," said Ruben Martinez.

The vast area is several hundred acres in size. "It is dirt roads, it is somewhere no one could hear anything," said Martinez.

A man who lives in the area told searchers on the day Carrillo went missing his daughter noticed a suspicious man walking the trail in hipwaders. He says anglers use the trail, this man didn't have a fishing pole.

Another neighbor told the group she didn't know and didn't recognize Andrew Hudson.

"Going to let the police do the great job they're doing, and we are going to help them search," said Martinez.

Investigators are asking that if anyone knows were Carrillo is or has heard from her to contact the Wyoming Department of Public Safety at 616-530-7300 or Silent Observer at 616-774-2345.
