Updated: Suspect in Thurston County homicides ‘shot the wrong people’; second suspect arrested after chase

Two men accused of killing two teenagers in a drive-by shooting in Lacey will be held without bail until their cases are resolved, Thurston County Superior Court judges ruled last week.

Hours after Trequanne Trenelle Wilson-Mason, 20, had his preliminary hearing on first-degree murder and drive-by shooting charges on Wednesday, Nov. 19, police located a second suspect in Pierce County and arrested him following a brief chase.

Jaden H. Johns, 20, of Olympia, was booked into the Thurston County Jail on first-degree murder and drive-by shooting charges Thursday morning after being evaluated at a local hospital.

Johns had his preliminary hearing Thursday afternoon.
The two men are accused of murdering brothers Alexander Borgen, 16, of Lacey, and Deven Borgen, 17, of Rainier, in a drive-by shooting on Friday, Nov 14.

Wilson-Mason allegedly admitted to police that he mistook Alexander Borgen for a different man accused of shooting Wilson-Mason’s house and dog in October.

He reportedly learned the victims’ identities several days after the murder and became “emotional after realizing he shot the wrong people,” according to court documents.

Johns is accused of driving the SUV that Wilson-Mason allegedly shot the Borgen brothers from.

The boys were reportedly walking home from a Shale Street Southeast address when they were gunned down at 24th Avenue Southeast and College Street Southeast at approximately 1:50 a.m. on Nov. 14.

“My kids are very good boys. They did not deserve to be walking home and get blasted by some evil freaking person,” the boys’ mother, Christina Borgen, told the court during Wilson-Mason’s preliminary hearing Wednesday afternoon.

When asked by Judge Allyson Zipp for her requests regarding Johns’ conditions of release on Thursday, Christina Borgen said that, while it wouldn’t bring her children back, she wanted Johns and Wilson-Mason “to rot.”

“I don’t want them out,” she said.

The two suspects face two counts each of first-degree aggravated murder while armed with a firearm and two counts of drive-by shooting connected to the Borgen brothers’ deaths.

“The allegations are the most serious offenses in our state. They are punishable by up to life in prison,” Judge Joe Skinder said during Wilson-Mason’s preliminary hearing in Thurston County Superior Court on Wednesday.

Skinder also found probable cause to charge Wilson-Mason with one count of second-degree unlawful possession of a firearm, tampering with physical evidence and violation of a domestic violence no-contact order.

Zipp found probable cause Thursday to charge Johns with one count of attempting to elude a pursuing police vehicle, in addition to the murder and drive-by shooting charges.

Both suspects had arraignment hearings scheduled for 9 a.m. on Tuesday, Nov. 25.

Police investigation
Wilson-Mason was arrested in Wenatchee on Tuesday, Nov. 18, and was booked into the Thurston County Jail at approximately 1 a.m. on Wednesday, Nov. 19, following an investigation helmed by the Lacey Police Department.

Lacey police responded to reports of shots fired and two subjects down on the roadway at 24th Avenue Southeast and College Street Southeast in Lacey at approximately 1:50 a.m. on Nov. 14.

Officers responded and located two unresponsive males with apparent gunshot wounds. Officers rendered aid and summoned medics, who continued life-saving efforts. Both subjects, later identified as the Borgen brothers, died at the scene.

Detectives reportedly located 26 9mm shell casings at the scene and confirmed that Alexander Borgen had more injuries than his brother.
According to an affidavit of probable cause filed in Thurston County Superior Court on Wednesday, surveillance footage from the area shows a light-colored SUV turn right from Belair Drive Southeast onto northbound College Street at about 1:36 a.m. and shows the Borgen brothers stop to allow the vehicle to pass them before continuing to walk the same direction.

The SUV reportedly turns off its headlights and loops back around to the Belair Drive Southeast and College Street intersection. The SUV’s headlights turn back on when it turns back onto northbound College Street at about 1:45 a.m.

The shooting is then captured on camera at approximately 1:46 a.m. “Rapid fire gunshots” were reportedly heard, according to court documents.

At 1:47 a.m., the SUV is seen making a U-turn and traveling southbound on College Street at a high rate of speed before turning onto Belair Drive Southeast.

A “shadowy figure” is then seen entering a house in the 4600 block of Belair Drive Southeast, according to court documents.

While investigating the Belair Drive Southeast address, law enforcement personnel learned that there had been an investigation into one of the home’s residents — Wilson-Mason — in February after he allegedly pointed a firearm at a woman.

During that investigation, police recovered multiple firearms, including a Glock 22 .40 caliber handgun that had been modified to be a fully-automatic weapon, according to court documents.

Detectives were reportedly able to track the number they had on file for Wilson-Mason’s cellphone and determined that the movement of his phone on Nov. 14 was consistent with the suspect vehicle’s.

Investigators later observed a man they identified as Wilson-Mason inside an SUV parked at the Belair Drive Southeast address.
Investigators reportedly followed the vehicle from Thurston County to Wenatchee on Nov. 17 and saw Wilson-Mason, two women and a small child check into a hotel room.

They conducted surveillance on the room overnight and arrested Wilson-Mason the next day, on Nov. 18, according to court documents.
Wilson-Mason allegedly provided a statement to law enforcement admitting that he was the shooter.

He allegedly said he was a passenger in a rented SUV that Johns was driving when he saw Alexander and Deven Borgen walking by near the intersection of Belair Drive Southeast and College Street.

Wilson-Mason allegedly mistook Alexander Borgen as another person, who was accused of “shooting up” Wilson-Mason’s home in October 2024 and injuring his dog.

“Wilson-Mason wanted to make the individual he thought was the shooter pay for the shooting,” the Thurston County Prosecutor’s Office states in the affidavit of probable cause, citing information relayed by law enforcement.

Wilson-Mason allegedly said he had Johns drive past the brothers “because he wanted to make sure it was the person,” and reported that he was “99% positive” that Alexander Borgen was the shooter from the October incident.

Johns allegedly said “I got you” and gave Wilson-Mason a handgun modified with a switch to be fully automatic.

Wilson-Mason allegedly took the gun from Johns and fired a total of 27 rounds out the front passenger window, aimed at a subject wearing a ski mask. That subject was later determined to be Alexander Borgen. He allegedly said he did not intend to shoot the other subject, who was later determined to be Deven Borgen.

Johns then allegedly dropped Wilson-Mason back at home, with Wilson-Mason reportedly leaving the gun in the car. He allegedly admitted to deleting security footage of his arrival from his home’s security camera, according to court documents.

He then reportedly called someone and went to Seattle with her, another woman, and his 3-year-old daughter. They reportedly stayed in a motel for 12 hours before returning to Lacey, collecting their belongings and going to Ocean Shores for the weekend, leaving on Monday, Nov. 17.

They then reportedly returned to Lacey, where investigators identified their vehicle and followed it to Wenatchee.

Back in Lacey, investigators executed a search warrant on the Belair Drive Southeast residence and interviewed the occupants, who confirmed Wilson-Mason’s account.

One of the women that Wilson-Mason was with in Wenatchee was confirmed to be the victim from the February domestic violence case, according to court documents.

Wilson-Mason was wanted on a felony warrant for violation of a domestic-violence no-contact order relating to that case at the time of his arrest on Wednesday.

His bail for that case has been revoked, meaning he will remain in custody until that case is resolved.

Second suspect’s arrest
Investigators looked into Johns’ car rental history, and found that he was due to return a white 2018 BMW X3 in Puyallup by 10 p.m. on Nov. 19, according to court documents filed on Thursday.

Thurston County SWAT made a move to arrest him in Pierce County shortly before midnight on Wednesday, Nov. 19.

Johns “was believed to be armed with an automatic weapon” at the time, according to Thurston County Sheriff Derek Sanders.
Deputies located Johns in the rented BMW and attempted to box him in, but he was able to escape and fled at a high rate of speed, according to information from Sanders and the Washington State Patrol.

Sanders reported that a TCSO SWAT operator deployed a Grappler, but the line snapped and the suspect continued to flee.

Johns was traveling eastbound on state Route 517 at 117 mph when a deputy conducted a PIT maneuver, ending the pursuit.
Johns’ vehicle struck the right side barrier and rolled, landing on its wheels and ejecting Johns.

He was not wearing a seat belt when his vehicle was struck, according to a Washington State Patrol incident report.

He sustained minor injuries and was transported to a local hospital before being booked into the Thurston County Jail, according to Sanders.

An AR15 with a 60 round magazine was also ejected from the vehicle, with numerous additional firearms observed in the car.

The patrol vehicle sustained no damage from the PIT maneuver and no deputies were injured, but the roadway was blocked for about five hours, according to Sanders and the Washington State Patrol.

State Patrol troopers responded to the crash, which occurred near milepost 7 on state Route 517 near Puyallup.

“Great work by all of the involved agencies in this operation to get a dangerous criminal off our streets,” Sanders posted to social media Thursday morning.
