An Irishman has reportedly been arrested in relation to the murder of a 31-year-old American tourist in Budapest, Hungary.
Mackenzie "Kenzie" Michalski, a nurse practitioner from western New York, was last seen at a nightclub in the Hungarian capital on Tuesday.
Police subsequently arrested a man who was seen with her at several nightclubs on the night of her disappearance.
According to US media reports, the suspect is a 37-year-old Irish citizen who has allegedly confessed to killing Ms Michalski. The reports claim he then showed police where he had hidden her body.
The US State Department said it is aware of reports that Hungarian police have arrested a suspect in relation to Ms Michalski's death, and that the US embassy is in contact with Hungarian police.
Michalski's family and friends released a statement on Friday that said they are "deeply saddened to confirm a report published by Hungarian police announcing the death of our beloved Kenzie".
"Kenzie will forever be remembered as a beautiful and compassionate young woman who dedicated herself to caring for others and making the world a better place," the statement said. "As a nurse practitioner, Kenzie used her humor, positivity, and limitless empathy to help heal her patients and encourage family and friends alike."
