A man who police say killed a 15-year-old Utah girl after she refused to have sex with him has been arrested in connection with her death.

Daniel Robert Lehi Ferry, 31, was arrested early Monday on suspicion of first-degree felony murder in the death of Anne Kasprzak, whose body was found March 11 in Utah's Jordan River, Fox affiliate KSTU-TV reported.

According to the statement of probable cause, a witness told police she saw Ferry physically assault Kasprzak after she refused to have sex with him. The witness said she observed Ferry remove Annie's unconscious body from his home and leave in a vehicle. 

Kasprzak, a freshman at Summit Academy in Draper, was reported missing by her family on March 10. The girl was last seen leaving her Riverton home following an argument.

Ferry recently finished serving a 10-year prison sentence for shooting a man at point-blank range, according to the station.

"He’s obviously had a past where he’s been close, so I can’t say that it’s not possible, but at the same time I just don’t see it," the man's brother, Timon Ferry, told KSTU. 

The brother, who was at the home when police arrested Ferry, said investigators were taking photos of the hallway.

"They were taking pics in my hallway, so I assume they think something happened in my hallway. And we just barely started remodeling our floor, and they were wondering where our carpet was," Timon Ferry said. 

Kasprzak was a "fun-loving" girl who struggled with the divorce of her parents, her uncle previously told the station. 

"Within the last few years her parents had been divorced and remarried, and that was difficult for her," said Scott Little.
