The family of a missing Princeton University student called for more urgency in the search efforts Thursday, nearly a week after her disappearance.

Misrach Ewunetie, 20, was last seen around 3 a.m. Friday on the New Jersey university’s campus.

“We can take any help we can find,” her brother, Universe Ewunetie, said in an interview that aired Thursday on ABC’s “Good Morning America.” “We just want the law to be faster because time is of the essence.”

Misrach went missing shortly after returning home from a Thursday night event with the Princeton Terrace Club where she was a volunteer, her family said.

A suite mate claimed to have seen Misrach brushing her teeth at around 3 a.m. Friday, but her roommate said the 20-year-old wasn’t there about an hour and a half later.

Her phone’s location was most recently traced to a residence that would take more than 30 minutes to walk to, according to ABC News, which confused her brother.

“Princeton’s a big campus, and it’s very insular, so it’s very odd that her phone would be off-campus,” Universe told the morning show. “Like, everything is on campus.”

Misrach didn’t attend a scheduled meeting regarding an application for United States citizenship over the weekend, her family said.

Her brother has joined the search as the university ramped up its efforts in recent days.

“As part of the continuing efforts to locate missing undergraduate student Misrach Ewunetie ‘24, there is an increased law enforcement presence on and around campus including the use of a helicopter, drones and watercraft,” Prince University tweeted Wednesday.

In an update Thursday morning, Princeton confirmed that it was continuing to enlist additional law enforcement officials.

Ewunetie was last seen at or around Scully Hall, a residential building on the Ivy League school’s campus, said Princeton, where students are on a fall break this week.

“She is 5 feet, 4 inches tall and weighs 130 pounds,” the university tweeted. “She has brown eyes, black hair and light brown complexion.”

University officials urge anyone with information about the disappearance to call the school’s Department of Public Safety at 609-258-1000. The department first announced its search efforts on Twitter on Monday.
