The Ramsey County Attorney's Office charged 39-year-old Jeffery Trevino with two counts of second-degree murder in the disappearance of his wife, 30-year-old Kira Trevino, who has been missing for nearly a week.
"Although a body has not been recovered, we believe that the victim has been murdered by the defendant," Ramsey County Attorney John Choi said at a news conference.
According to the criminal complaint, Jeffery Trevino reported his wife missing on Sunday morning, claiming he hadn't seen her since Friday morning and that she did not show up to work at the Mall of America on Saturday.
He told police she was having a "mid-life crisis" and would leave their home for two or three days at a time.
After learning of her disappearance, Kira Trevino's mother told police that her daughter and Jeffery Trevino were having marital problems and she was concerned Jeffery Trevino might harm Kira.
Kira had expressed to friends and family that she was unhappy and talked about moving out over the past few months, according to investigators.
The complaint states the couple planned a "date night" last Thursday that included dinner and bowling at the Mall of America. They went home, watched a movie and went to bed.
Surveillance images show Kira's car, a white 2006 Chevrolet Cobalt, arrive at a gas station at Larpenteur Ave and I-35E around 2 a.m. Friday. Although the images are not clear enough to establish an identity, images show a man in gray pants and a gray hooded sweatshirt fill the car with gas and get back into the car. Wells Fargo Bank records show Kira's debit card was used at the gas station.
The car exited the gas station and headed toward the entrance of I-35E, instead of toward Larpenteur, which is the most direct route to the Trevino's home, according to the court document.
At 9:45 a.m., almost eight hours later, Mall of America surveillance video shows Kira's Chevy Cobalt enter the parking lot. Although the video is, again, not clear enough to establish an identity, the video shows a person at the back of the vehicle throw "an item consistent with the truck liner."
The person then walked to the Nordstrom's area and got into an Airport Cab that traveled less than a block away from the Trevino's home at 570 E. Iowa Avenue.
A search warrant was executed at the home on Monday. Investigators found freshly washed towels, towels stained with bleach, a mop, bucket and other cleaning supplies.
Investigators found "copious amounts of blood evidence" in the master bedroom, hallway and kitchen. A large section of the carpet in the master bedroom was cut out by the BCA crime lab and revealed a large blood stain on the underside in the shape of a human head and torso.
Blood was also found leading into the basement and the laundry area.
Forensic evidence found extensive cleanup efforts including more blood evidence on the wheels of a carpet cleaner.
Blood was also found around the trunk opening of Kira's car and on the trunk liner that was found a short distance away from where the car was parked.
Police arrested Jeffery Trevino on Tuesday.
Kira's body is still missing.
Jeffery Trevino made his first court appearance Thursday afternoon. Bail has been set at $1 million.
Choi says Jeffery Trevino has not been helpful in locating Kira's body.
Although it's difficult to pursue a homicide case with no body, it has been done on occasion in Minnesota, the Pioneer Press notes. Choi says he believes prosecution can prove the case beyond reasonable doubt.
MinnPost notes that Tad DiBiase, a former federal prosecutor who consults with police and prosecutors on homicide cases in which no body has been found, tracks the cases on his website nobodycases. On 378 cases he tracked, there was about an 89 percent conviction rate. DiBiase said that generally, the evidence that investigators most often rely on in such cases is a large amount of blood, MinnPost reports.
