The University of Utah sorority sister who disappeared after taking a Lyft ride more than a week ago was last seen climbing into another vehicle after she was dropped off, police said.

Mackenzie Lueck, 23, arrived at Salt Lake City airport on June 17 and called a Lyft to Hatch Park in North Salt Lake, according to Salt Lake City police.

Lueck, who is from El Segundo, Calif., was dropped off just before 3 a.m. at the park, where she got into another person’s vehicle with her luggage, authorities said.

“Detectives have spoken with the Lyft driver and learned that Mackenzie was met at Hatch Park by an individual in a vehicle,” Salt Lake City Assistant Police Chief Tim Doubt said. “The Lyft driver left Mackenzie at the park with that person and stated that Mackenzie did not appear to be in any type of distress.”

Doubt said they have unable to verify the make of the vehicle or a description of the driver.

Lueck’s roommates became concerned after she never arrived at their home near campus, which is a 20-minute drive from the park where she was last spotted, according to police.

Police said the college senior skipped an exam — and missed a Los Angeles-bound flight Sunday to attend a wedding.

“We don’t have any evidence that foul play has occurred but the circumstances of her going off the grid and not showing up for appointments and flights is concerning to us,” Doubt said.

Friends said the Alpha Omega Chi sister’s phone has also been shut off and she hasn’t been active on social media, according to news station KSL.

“We’ve been calling her phone nonstop,” said another sorority sister, Ashley Fine. “We’re millennials … Even if you’re missing, or you want to disappear, you have to turn your phone on to GPS.”
