Keizer police offer rewards for tips on missing Woodburn mom Cynthia Martinez

Keizer police announced Thursday two rewards for information leading to Cynthia Martinez, a Woodburn mother missing since last summer. 

Martinez, 26, was last seen leaving Tequila Nights, a bar and grill located at 3393 River Road North, with a man around 2:35 a.m. on July 16th, 2017.

In the hours leading up to her disappearance, Martinez attended a birthday party in the Woodburn area and arrived at the Keizer bar around 12:30 a.m. Sunday, according to Keizer police. 

Martinez was seen leaving the bar with two Hispanic men roughly two hours later. She joined the two men in a blue 2004 Honda Odyssey minivan and left the bar.

Investigators found the van the next day. She hasn't been seen or heard from since.

The Federal Bureau of Investigation is offering a reward of up to $8,000 and Crime Stoppers of Oregon is offering a reward of up to $2,500 for information leading to the location of Martinez or to the arrest and conviction of the person responsible for her disappearance. 

Keizer police identified Jaime Alvarez-Olivera, 30, as a person of interest in her disappearance in August, roughly three weeks after she disappeared. 

Officials believe Alvarez-Olivera left the Marion County area on July 16 shortly after Martinez was last seen with him. 

He is believed to have lived in the Woodburn area, but police have not been able to locate him.

Deputy Chief Jeffrey Kuhns told the Statesman Journal in August that Keizer Police detectives were unsure whether he has left the country.

The second man seen leaving the bar with Martinez and Alvarez-Olivera is cooperating with investigators. Police have declined to identify him.

Alvarez-Olivera was last employed as a farm laborer who harvested berries. Kuhns said he worked for a labor firm where he would call in every morning and would be directed to different labor jobs on a daily basis.

In August, Keizer police asked to speak with anyone who might have seen the minivan or captured the vehicle on surveillance or trail cameras between Sunday, July 16 around 2:30 a.m. and Monday, July 17 around 11:45 a.m. in any rural, farmland or forested areas northeast of Keizer, Brooks, Lake Labish, Silverton, Mt. Angel, Scotts Mills or Molalla.

Keizer police officials said in August that they've spent more than a thousand hours investigating Martinez's disappearance with the help of the FBI,  the Oregon Department of Justice, the Marion County District Attorney’s Office, and other local law enforcement agencies in both Marion and adjoining counties.

Martinez is described as being 5 feet 1 inch and 135 pounds with dark brown eyes and black hair. She has two prominent tattoos on her chest that read "Dominguez" and "trust no one."

Anyone with information regarding Martinez's disappearance or anyone who has had contact with Alvarez-Olivera on or after July 16, 2017 should contact the Keizer police tip line immediately at 503-856-3529.
