Lundyn Treese, 17, was ejected and killed in the crash that occurred about 4:09 a.m. Sunday on the 900 block of the 10th Avenue expressway. While police have yet to officially name the student who was killed, Treese was identified by a number sources and was named as the victim in a GoFundMe page set up by her aunt and on a cross and teddy bear left at the crash site.

City police have charged Jared Paul Detwiler, 19, of Altoona with homicide by vehicle while DUI in connection with the crash, according to online court documents.

Detwiler will be served with an arrest warrant upon his release from the hospital where he is being treated for injuries he suffered in the crash, including fractured vertebrae and a broken foot, according to the Altoona police Facebook page and the affidavit of probable cause.

Detwiler was driving a 1500 Dodge Ram truck in the far left lane of the expressway at its beginning near Ninth Street, when the truck swerved across the middle and right lanes and into a shrub, a tree, a post and four vehicles in the parking lot of Green Avenue Towers — ejecting both Detwiler and Treese, who was in the passenger seat.

A 17-year-old passenger in the back seat climbed out of the truck unhurt, according to the report.

Detwiler ended up sitting in a grassy area, smelling of alcohol, slurring his speech and claiming that he’d swerved to avoid a car that had cut him off, when officers responding to the crash first encountered him — but later examination of security footage from the tower showed that “at no point did any vehicle swerve in front of the defendant,” according to the affidavit.

Blood tests showed that Detwiler’s blood alcohol was 0.218 percent, 2.7 times higher than the 0.08 percent legal limit in Pennsylvania for drivers over 21, according to information in the affidavit. The blood alcohol limit for drivers under 21 in Pennsylvania is 0.02 percent.

During the investigation, police learned that Detwiler was driving a truck owned by the grandmother of a 16-year-old witness who, earlier that night, was at a college party on Grandview Avenue. The witness said the location is known as “Sigma” and they were there with other juveniles, including the victim. It was at the party that the juveniles met with Detwiler, according to court documents.

The 16-year-old knew Detwiler from previous underage parties, including at “Sigma,” and gave the keys to the truck to Detwiler before going to a different party in Hollidaysburg, according to court documents.

Later, at a house on Coleridge Avenue where another 17-year-old lived, the 16-year-old and Treese were present when Detwiler showed up in the truck with another 17-year-old.

The 16-year-old and 17-year-old witnesses were outside when Detwiler arrived and told him that he could not park in the driveway. Treese then exited the residence and got into the truck with Detwiler and the 17-year-old passenger, the report states.

Detwiler and Treese “were talking when suddenly they crashed,” according to the 17-year-old juvenile riding in the back seat of the truck, the affidavit states.

The 16-year-old and the 17-year-old witnesses came to the scene after the crash as a result of information provided by the Life 360 app, according to the affidavit.

That app “can detect major collisions and alert the circle of contacts,” according to the Life 360 website.

In addition to homicide by vehicle while DUI, Detwiler faces felony homicide by vehicle and aggravated assault by vehicle charges, along with misdemeanor charges of DUI highest rate, DUI general impairment and recklessly endangering another person, and summary charges of purchasing alcohol by a minor, disregarding traffic lane and driving at a safe speed.

A state police trooper processed the accident scene, according to the affidavit.

The AAHS girls soccer team had been scheduled to play a subregional playoff game against Pittsburgh Taylor Allderdice High School at Allderdice on Monday, but due to the death of the Altoona player, the game was rescheduled for today at Mansion Park, according to Altoona Area School District spokeswoman Paula Foreman.

The district is grateful for the other district’s consideration, Foreman said.

“Allderdice showed great sportsmanship … (Great) understanding, caring and mutual concern,” Foreman said.

AASD Athletic Director Phil Riccio discussed options with the team after the accident, and the players felt “it was important to continue to finish the season as best they could,” Foreman said.

But postponing the game for a day and playing it at home, thus eliminating the need to travel and allowing for more support from fellow students, “makes it easier on our girls,” Foreman said.

The game is a play-in contest, with the winner earning a place in the formal playoff bracket, Foreman said.

The school district is providing counseling and grief support at the high school for any student or staff member who may need additional support at this time, Superintendent Brad Hatch said in a message to parents.
