"Her favorite blanket was crumpled up on the floor and I was very scared."

That's what Vickie Felton told CNN about the moment she walked through her own home and realized her 13-year-old daughter was gone. It had been less than an hour. And in the 34 years since, no one has ever been arrested.

A Storm, an Empty House, and a Phone That No One Answered

On the morning of August 27, 1992, the remnants of Hurricane Andrew were pushing through Tupelo, Mississippi. Inside a small house on Honey Locust Drive, 13-year-old Leigh Occhi was home alone, still in her nightgown, getting ready for an open house at her middle school later that day.

Her mother, Vickie, left for work a little before 8 a.m. Once she got to the office and learned the storm was closing in, she called home to check on Leigh — using a code the two of them had, two rings and a hang-up, so Leigh would know it was safe to pick up.

There was no answer. She called again. Still nothing.

So Vickie got in her car and made the mile-and-a-half drive home. She'd been gone less than an hour. When she arrived, the garage door was open — and the automatic garage light, which turns off after five minutes, was still on. Whatever had happened, it had happened only minutes before she pulled into the driveway.

Leigh was gone.

What Vickie Found Inside

Inside the house, Vickie found blood smeared on the wall. She went room to room, calling for her daughter, but the home was empty.

She called police at about 9 a.m. What investigators found when they arrived was a scene that has haunted this case for over three decades. Fresh, still-wet blood stains marked the walls, the carpet, and the bathroom countertop. Blood and hair were found stuck to a door frame — evidence, investigators believed, that Leigh's head had struck it, possibly more than once.

Leigh's nightgown was later found bloodstained in a laundry basket, along with a bloodstained bra. Based on how the blood had dripped down onto the fabric, investigators believed the injury had been to her head.

And in the bathroom, someone had tried to clean up. But no rag or towel was ever found in the house. Whoever cleaned up took the evidence of that cleanup with them.

The Missing Outfit, the Missing Glasses

There was no sign of forced entry. Both of Leigh's parents were certain of one thing: she wouldn't have opened the door to a stranger.

At some point during the attack, Leigh either changed clothes or was undressed and redressed by someone else. A brand-new outfit — including a bra and underwear she'd received for her birthday just the week before — was missing from the house. So were her glasses, and a sleeping bag she always kept in her room.

Bloodhounds were brought in, but Hurricane Andrew's remnants made tracking nearly impossible. Organized searches of the surrounding woods turned up nothing. DNA testing was still in its infancy in 1992, so all investigators could rely on was blood typing — and every sample from the scene matched Leigh's type.

The Envelope From Booneville

Eight days after Leigh disappeared, a McDonald's employee about 30 miles north of Tupelo, in Booneville, Mississippi, reported seeing a girl who looked like Leigh at the drive-through. The tip led nowhere. It was another child.

Then, five days after that — thirteen days after Leigh vanished — an envelope arrived at the house on Honey Locust Drive. It was addressed to Leigh's stepfather, with both his name and the street name misspelled. It carried six stamps, twice the postage needed, and was postmarked from Booneville.

Inside were Leigh's missing glasses. But there was no note. There was no ransom demand. Just the glasses, with no explanation.

The FBI took over forensic analysis, sending the envelope straight to Quantico. Handwriting analysis went nowhere. There were no fingerprints. The stamps had been moistened with water rather than saliva, closing off any hope of recovering DNA.

The lead detective on the case, Bart Aguirre, later said he believed the glasses were a deliberate distraction — that a genuine kidnapper would have asked for something in return. He would later tell CNN that envelope was the last real clue this case ever produced.

A Devastating Case of Mistaken Identity

Fourteen months after Leigh disappeared, a farmer discovered a human skull in a ditch near a soybean field in Monroe County. Dental records led the coroner to positively identify it as Leigh.

Days later, that identification was retracted. The examiner's office had been working from outdated records. The skull actually belonged to a 27-year-old woman named Pollyanna Sue Keith, who had gone missing from a neighboring county seven months later.

For Leigh's family, it was a false hope raised and then taken away within days.

The People Closest to Leigh

Leigh's stepfather, Barney Yarborough, had separated from Vickie about a month before Leigh disappeared and was no longer living in the home. He passed a polygraph and had what investigators have described as an airtight alibi. He died of cancer in 1996, at just 34 years old.

Leigh's father, Donald Occhi, was stationed in Virginia at the time and didn't learn his daughter was missing until the following day — and even then, he says Vickie initially told him only that Leigh had run away, with no mention of blood or a crime scene. He passed a polygraph and was ruled out as a suspect. He spent about a month in Tupelo searching fields and woods until his leave ran out. His theory has never wavered: that someone attacked his daughter inside that house, and that she never left Tupelo.

He's also said that while he searched, multiple locals quietly pulled him aside and told him to look closer at Leigh's mother.

Where This Leaves Us

Vickie Felton has never been charged, and has never been officially named a suspect. She has always maintained she had nothing to do with her daughter's disappearance. But she failed a police polygraph — and two more administered later by the FBI. In 2017, on the 25th anniversary of Leigh's disappearance, Bart Aguirre — by then the police chief — told a reporter he still considered her a person of interest, telling them there were still too many unanswered questions about her actions that morning.

But Vickie herself has spent decades pointing at someone else entirely — a man named Oscar McKinley Kearns, known to those who knew him as Mike.

That's where Part 2 of Leigh's story picks up.
