A shocking break was made in the case of 20-year-old Kaylyn Whitaker whose death in 2014 was initially considered a suicide, officials said.

More than four years after his girlfriend’s death, Connor Scott reportedly walked into a police station Sunday evening in central Indiana and confessed to killing her, according to news station WTHR.

Scott, 24, is accused of shooting Whitaker at his home in Martinsville, Illinois, on Halloween in 2014.

His girlfriend’s death was originally investigated as a suicide, but it was ruled a homicide about 10 months later.

The motive behind the shooting — or Scott coming forward more than four years later — wasn’t released.

Whitaker’s parents said Monday they were shocked to learn Scott turned himself in to authorities.

“I wouldn’t have guessed,” her dad Dave Whitaker told MyWabashValley. “I really thought he thought he was going to get away with this.”

The slain 20-year-old’s parents said they don’t doubt Scott cared for their daughter.

“He loved Kaylyn,” her mom Leslie Roberts told the site. “He just made a really bad choice.”

Scott was booked at Hendricks County Jail while he awaits extradition to Illinois.
