Woman arrested after being held at knifepoint in Rainier, Oregon, robbery

Posted

The woman held at knifepoint by her ex-boyfriend during a robbery at a Rainier, Oregon, convenience store now faces charges related to the Dec. 12 strongarm heist.

Columbia County Circuit Court documents show Tatiana Alzatti Martinez, 35, of Longview, pleaded not guilty last week to 12 criminal counts, including six theft charges, in the first-, second- and third-degrees. She also faces three counts of first-degree robbery and three counts of menacing.

According to a Columbia County Sheriff's Office notice, she was indicted by a grand jury after authorities reviewed security footage of the incident, which allegedly showed her involvement in the crime.

She must refrain from any contact with the victims as well as her co-defendant and ex-boyfriend Kristopher James Mann, 36, of Longview, and must stay away from the site of the robbery: Rainier Deli and Mart, 75930 Rock Crest St.

Her bail was set at $80,000, and her next scheduled hearing is on Jan. 14. 

Mark J. Lang, of the St. Helens-based law firm Lang and Associates, represents Martinez and filed a motion seeking his client's conditional release while legal proceedings are ongoing.

Martinez told authorities that Mann directed her to tell a Deli and Mart employee to place the cash in a bag, then proceeded to hold her at knifepoint, court records show. She said she thought Mann would cut her and made a motion with her hand towards her neck, according to a report on Mann. 

Right after the robbery, she told a Columbia County Sheriff deputy that she didn't know the masked suspect robbing the Deli and Mart on Dec. 12 was her ex-boyfriend, according to court records. However, the deputy noted in her report that her story "did not make sense" and planned a follow-up interview.

Mann was indicted on 10 counts, including three counts of first-degree robbery and three counts of first-degree theft. His arresting documents state he held a knife to his ex-girlfriend's neck as he demanded an employee hand over $2,200.

Mann also allegedly took a phone valued at $100 from another person in the store, and $1,060 from his ex.

He then ordered everyone in the store to hand over their phones and lay on the ground. He told them to hand over their IDs so he would know where they live, court records show. 

He has a hearing on Feb. 2, with a potential trial on Feb. 10.
