A 25-year-old man killed five people in an Austrian ski town when he opened fire at his ex-girlfriend’s home, according to reports.

The suspect, who has not been named, admitted to officers that he killed his 19-year-old ex-girlfriend, her family and new boyfriend in the town of Kitzbuehel, Austria’s Kurier newspaper reported.

“I have just murdered five people,” he allegedly said to officers before surrendering a pistol and knife to them.

The alleged perpetrator had broken up with the woman two months before the Sunday morning slayings.

On Saturday night, he ran into his ex-girlfriend and her new beau and they got into an argument, police said.

He later showed up twice to her family’s home in the wealthy ski town early Sunday, returning the second time with his brother’s pistol, officials said.

The jilted ex allegedly used the weapon to fatally shoot her father as the man opened the door.

He then shot dead the woman’s 25-year-old brother and mother before climbing over a balcony to break into his ex’s attached apartment, where he killed the teen and her 24-year-old boyfriend, authorities said.

“We are all shocked and deeply saddened,” Kitzbühel mayor Klaus Winkler said, according to German news outlet Deutsche Welle.
