US woman, 21, found dead in her apartment after stalker she met on Tinder put GPS tracker on her bike

A WOMAN from Massachusetts who was studying in the Netherlands has been stabbed to death by a stalker she met on Tinder.

Mieke Oort, 21, of Winchester, was attacked inside her apartment above a tattoo shop in Leeuwarden, Sunday morning, by the suspect who has only been identified as Thomas R, 27, from Leek.

Oort only recently moved into the apartment in the town, which is around 90 minutes away from Amsterdam, following a breakup with her boyfriend of two years Michael van der Waal.

She is said to have only dated Thomas R briefly.

Oort met Thomas R through Tinder but he reportedly became violent and started stalking her after she got back with Michael.

Thomas R is said to have harassed Oort via WhatsApp, driven up and down her street and put a GPS tracking device on her bike, according to van der Waal, speaking to local news outlets.

Oort’s family has flown to the Netherlands to make arrangement for their daughter in the aftermath of her death.

“She was my baby sister. We don't really know how to cope with it,' her sister Danique told . “She had just so much more to give and she had a lot of love for everyone.

“She was the sweetest, strongest woman I knew. She really just put everyone else before her. Everyone.”

“Right now, we're just trying to process this whole situation, and really say our goodbyes and make the necessary arrangements will have to do,” her sister added.

Cops received a call about a fire in her apartment on Tweebaksmarkt in Leeuwarden at around 3.30am Sunday.

Oort’s body was discovered after the fire had been extinguished.

Two other men who lived in the building, aged 25 and 30, suffered mild to serious injuries.

The fire is said to have been started by Thomas R after he threw and incendiary bomb against the house to force the other residents out and a fight is said to have broken out between two male residents.
