Since the October 11th, 2019, robbery, Medford Police Detectives have been actively investigating the case. The investigation has revealed the following:

On October 11th, 2019, shortly after 8:00 a.m., the 28 year old female victim, and her 25 year old boyfriend reported they had been robbed at gunpoint in their motel room at the Econolodge, 1015 S. Riverside Avenue. The three suspects, one of them armed with a gun, entered the motel room, pistol whipped the 25 year old boyfriend, stole property, and jumped into a 2008 VW SUV in the parking lot. The victim couple attempted to block them in with their vehicle, but the suspect vehicle rammed them, before fleeing the parking lot.

The victim couple chased them in their 1998 white Mercedes sedan. During the car chase, the victims crashed and became disabled near E. Main Street and Eastwood Avenue. As previously mentioned in the press release, witnesses attempted to follow the suspects but lost it. 

The victims reported that the suspects stole over $100,000 in gold coins as well as cash and electronics.

On October 12th, 2019, the suspect vehicle was found in the 2700 block of Payne Road, Phoenix, after a citizen called it in as suspicious. The vehicle was unoccupied and seized for evidence. 

Through the investigation, detectives were able to identify two of the suspects as Sadele Threets, 30 years old, and Dustin Mack, 30 years old. Threets was the one armed with the handgun. 

On October 16th, 2019 at about 3:00 p.m., Medford Detectives were alerted to individuals attempting to sell gold coins at various local coin stores, which matched the unique coins stolen in the robbery. Detectives conducted surveillance and located the suspects in question near 8th Street and Grape Street, leaving a local coin store. Detectives followed two involved vehicles as they drove away together. While they were stopped in traffic on McAndrews, west of Biddle, a Medford Police Officer and two detective vehicles attempted to box them in. One vehicle fled while the other remained on scene. The vehicle that fled was a white 2006 Mercedes 230. The vehicle eluded officers northbound on Biddle Road, in the southbound lanes of travel. The driver of the vehicle that remained stopped, Mariha Lynn Mack, 24, was arrested on outstanding warrants.

Officers flooded the area but lost the vehicle on Poplar Drive, between Progress Drive and Hwy 62. Various witnesses pointed out three subjects running in an eastbound direction. Officers were eventually able to capture three suspects on Steelhead Run Drive, off of Corona Avenue. The suspects were Dustin Mack, 30, Matthew Andress, 35, and Michelle Kleiser, 37. All of the suspects had outstanding warrants and Mack was wanted for the original robbery.

The elude vehicle was located in the 2100 block of Poplar Drive and towed for evidence. 

The investigation led detectives to the 3000 block of Lone Pine Road, where Sadele Threets was thought to be residing in an Airbnb. The residence was surveilled and detectives saw Threets leave the home and get into an Uber. The Uber was stopped on McAndrews Road and Ross Lane. Threets was arrested without incident and was in possession of property stolen in the robbery. The gun was not recovered. Approximately half of the $100,000 in gold coins has been recovered.
