The Sutter County Sheriff’s Office will be taking the lead in the investigation into the disappearance of a 20-year-old Gridley woman.

Alycia “Aly” Yeoman has not been seen since about 11 p.m. Thursday, March 30, when she left a party in the 1800 block of Romero Street in Yuba City.

Friday afternoon at the Sutter County Courthouse, local authorities held a press conference to give an update on the status of the investigation.

The Sutter County Sheriff’s Office will be taking over the investigation, leading a Unified Command Team that involves several area law enforcement agencies, including the Gridley-Biggs Police Department.

 The FBI has become involved with the case, and a $5,000 reward is being offered for information leading to Aly’s recovery. A GoFundMe account has been set up with $8,833 raised as of press time Tuesday to help in the significance of the reward.

A number of members of Aly’s family attended the press conference Friday afternoon in Yuba City, as Gridley-Biggs Police Chief Dean Price read a statement from them.

“We firmly believe in our hearts that Aly is alive and needs our help,” the family said in its statement. “Aly, if you are hearing this, we have come all across the country. We love you and are desperately doing everything we can to bring you home safely.”

Authorities have executed a search warrant for the home, and recovered Aly’s vehicle, a 1998 Toyota Tacoma pickup truck, along with her cell phone in a Live Oak orchard April 3. They also found a single set of footprints walking away from the vehicle.

The FBI’s tip line can be accessed at 1-800-CALL-FBI.

Anyone with information on the case can also call the Sutter County Sheriff’s Office at 530-822-7307.

Meanwhile, there are two other cases of missing young girls in Sutter County that authorities say are unrelated to the Yeoman case.

Annalise McClanahan-Calvert, 16, disappeared from a Live Oak church last Wednesday night, but has reportedly contacted her parents since in a phone call Sunday night. Her case is still being treated as a missing persons case.

Ariana Torres, 16, of Yuba City, has reportedly been missing since February 10 of this year. Torres is 5-4, 160 pounds, with light brown hair and brown eyes. She is biracial (Hispanic and white).
