The investigation has revealed that after the dogs were located, a police officer at the Evanston Police Department in Wyoming conducted a traffic stop on the victim’s vehicle, a dark blue Toyota Rav4, at 2:00 a.m. on July 11. At the time, Tavar had not been reported missing and Roberts, who was driving, was given a verbal warning for excessive speed. The victim was not in the vehicle at that time.

Approximately 12 hours later, Roberts entered a Wal-Mart in Ontario, Oregon where he purchased a tent, a vintage styled black t-shirt and tan cargo shorts. He was also seen in the store wearing a dark colored t-shirt and tan colored shorts. Roberts also filled the gas tank on the Toyota Rav4 before leaving Ontario.

A Nationwide alert has been issued for the suspect and the victim as the investigation continues. In addition, the victim’s family has offered a $25,000 reward for information leading to the arrest of Roberts for the outstanding warrant. Roberts is described as a white male, 26 years old, 6’1" tall, 170 pounds with brown hair and hazel eyes. Tavar is a white female, 45- years-old, 5’7" tall, 120 pounds with blonde hair and brown eyes. The 2004 Toyota Rav4 has a Florida license plate of Q66 2NJ.
