The Princeton student who was found dead on campus died due to an overdose of antidepressants and an antihistamine.

The coroner ruled the death of Misrach Ewunetie, 20, a suicide.  

Ewunetie, a junior sociology major from Euclid, Ohio, was found dead by the university's tennis courts on October 20 after she was reported missing the week prior. 

The Middlesex Regional Medical Examiner's Office determined she died from an overdose of 'bupropion, escitalopram and hydroxyzine.' 

Bupropion and escitalopram are both antidepressants, and hydroxyzine is an antihistamine that can be used to treat anxiety.

Despite her death being ruled a suicide, Princeton students may still fear a murderer is amongst them after it was revealed another student's dorm room door was removed from its hinges by an an unknown man who also left a note that read 'be nicer' shortly before Ewunetie's death. 

Princeton officials have said that the campus is safe, but earlier this month, students expressed they were still concerned, especially in light of the fact that the note that was left on the same day of Ewunetie's disappearance. 

It is not common to overdose on antidepressants alone, but in combination with opioids the likelihood of an overdose increases.

It is also possible to overdose on antihistamines, which are usually found in allergy medication, and can used to treat anxiety. 

A person would have to consume three to five times the recommended dosage in order to overdose on an antihistamine.

As for antidepressant overdoses, it is most common that people are also found with opioids in their system. 

Around 5,500 Americans died of overdoses that involved antidepressants in 2020. Less than half of them, however, did not also take opioids. 

Without the presence of opioids, it is much less likely for a person to overdose on antidepressants alone. 

A person has an increased chance of an antidepressant overdose by taking more than one drug that affects serotonin. 

The eerie note was found on sophomore Mikayla Merin's door.

Merin told the New York Times that the incident left her so unsettled that she took a month off of school and only returned after installing her own security camera in the room. 

Student Faeven Mussie told the Times that it was premature for the school to make such claims when so little information has been released about the death.

The fact that Ewunetie's body was found in a secluded location, that her phone last pinged off campus, and that another student found her door removed from its hinges with a warning note attached the same day of the disappearance, have left students chilled.

'We don't know what to think or what to believe or if we're safe here,' Mussie, who spoke on behalf of the Ethiopian and Eritrean Student Association, said.

Ewunetie's family has expressed their frustration over the lack of details and condemned police for keeping them in 'the dark.' 

Prior to the autopsy report, police attempted to quell fears by lamenting that there was 'no obvious signs of injury' and that it did 'not appear suspicious or criminal in nature.' 

The university also sent out notices to students that there was no evidence that Ewunetie's death was a murder.

In that notice, however, the school said it was tightening up security on campus, as well as enhancing lighting at night and security-camera programs.

'While we know that our campus is safe, it's important that you also feel safe,' officials had written to students at the time.

Misrach had been volunteering at Princeton's Terrace Club, one of the school's 11 private eating clubs, on October 13.

Terrace Club is one of the non-private clubs at Princeton, requiring members to only sign up for membership, and is not associated with the university. The clubs are for upperclassmen at the school to eat lunches and participate in various activities.

Other clubs require prospective members to apply for membership.

She was a member on 'duty' — performing housekeeping tasks during a live music performance at the club.

That night, the club was hosting Raavi with Jackie Marchal, according to its Instagram page.

After the club had closed and all of the responsibilities had been fulfilled, Ewunetie, together with other members on duty, left for the night.

Following the event 'she went back to her dorm at 3am' her brother Universe said. 'Her roommates said they saw her at 3am. Then another roommate of hers said she didn't see her after 4am, and then after that no one had seen her.

Ewunetie's disappearance triggered a multi-day hunt for her whereabouts that resulted in drones, helicopters and watercraft vehicles being deployed around the Ivy League university.

Campus police had visited Ewunetie's housing estate three times and conducted a search with dogs, but were unable to enter any properties due to a lack of search warrants.

It was previously revealed that her cell phone last pinged early Sunday morning from a location seven miles from the campus.

The ping was located at a New Jersey housing complex near Penns Neck.
