TEMPE, Ariz. - A man and his wife have been arrested in connection with the murder of 45-year-old Jason Johnson, the suspect's co-business owner, who was reported missing on Monday.

Family members filed a missing persons report on Monday when Johnson missed several weekend appointments and failed to show up for work on Monday.

The last time anyone had seen him was Friday night at his place of business, Scottsdale Auto Collision Center, at 7015 S. Harl Dr. in Tempe.

Tempe Police Detectives contacted coworkers at Scottsdale Auto Collision. They learned about a confrontation that occurred with Johnson and his co-business owner Chad Norris.

When detectives spoke with Chad and Tamara Norris, they say they were unwilling to cooperate.

Surveillance was conducted on Norris, and detectives observed the couple acting suspiciously that led them to believe "they were attempting to cover up a crime," Tempe Police say.

Chad and Tamara Norris were allegedly observed leaving their residence with a box trailer attached to the rear of an SUV. They then drove to an area in Phoenix and allegedly abandoned the trailer.

Detectives released a canine cadaver dog around the outside of the trailer, and the dog alerted to it. They obtained a search warrant for the trailer and inside, found a violent homicide scene, according to police.

Blood, spent shell casings, and a wallet containing Jason Johnson's driver's license were found inside the trailer.

Police believe that Johnson was killed and his body was hid in an unknown location. They arrested Chad Norris for second degree murder and Tamara Norris for felony hindering. They were booked into the Tempe City Jail.

Anyone with information is asked to contact police.
