Cameron Moser from Minnesota in the United States of America killed 46-year-old Bethany Bernatsky at the Cozy Bay Resort on Lake Edward.
The incident occurred at 11 pm on October 7.
He was booked into the Crow Wing County jail on Friday on a charge of second-degree intentional murder.
He is being held on a $1million bond pending his next court appearance on October 20.
Dailymail.co.uk reported Sheriff Scott Goddard as saying that investigators are trying to determine whether the killing was a case of mistaken identity, in which Moser intended to kill his 26-year-old ex-girlfriend, who is the daughter of the resort’s former owner.

It is suspected that Moser shot Bernatsky after mistaking her for his ex-girlfriend who happens to be the daughter of the resort’s former owner.
According to Minneapolis Star Tribune, Bret Jevning, who previously operated the Cozy Bay Resort claimed the suspect had come to his RV park across the street the previous week and was looking for his daughter.
Jevning said Moser was unhappy that his ex-lover has stopped taking drugs after entering rehab, and ‘he was taunting her by using [drugs] himself’.
Photos of Jevning’s daughter and her deceased friend available on social media reveal that despite their 20-year age difference, the two women shared similar features, including long blonde hair, similar height and build, according to the Daily Mail.
Law enforcement officers found Moser a few minutes after the shooting, carrying an AR-15-style rifle and a silver handgun across the street from the resort, at the Mollie Lake RV park.
He was arrested before SWAT team members went to inspect the resort and discovered Bernatsky lying face down in a large pool of blood at the end of a hallway in one of the cabins.
Investigator Phil Stanley, who found the victim’s body, ‘observed a large amount of apparent blood, tissue and bone matter surrounding the victim.’
She was transported to the Ramsey County Medical Examiner’s Office, where she was identified through a tattoo on her body.
An autopsy determined that Bernatsky died after being shot multiple times, including once in the head, reports say.
