For a moment, Ted just watched Karen sleep.

He'd pushed his obsession with peeping to its limit, but it wasn't enough for him.

All of the sudden, he ripped off a piece of her bed frame and swung it into Karen's skull.

Before she could even take a look at her attacker, Karen went limp, blood seeping into her mattress.

Ted sexually assaulted her, beat her even more, then left her for dead.

Once he finished, he sneaked back out as quietly as he'd entered.

for hours none of karen's housemates realized something was wrong it wasn't until 2 30 the following afternoon that someone noticed that she hadn't come out of her room one of the young men who lived with her peeked inside and saw karen bundled up in bed covered by a pile of blankets he figured she was sleeping and left her alone but five hours later so this would be around 7 30 p.m she was still there at that point someone went back in to check on karen

When she didn't answer, they pulled back her blankets and realized what had happened to her.

Miraculously, Karen was still alive, although she'd fallen into a coma.

She was rushed to the hospital as news spread around campus that a young woman had been attacked.

The police launched an investigation, but there wasn't much to go on.

Ted hadn't left anything behind at the scene.

And these were the days before DNA profiling.

Although Ted certainly hadn't planned for Karen to survive the attack, his horrific plan had otherwise gone just as he'd wanted.

Even after Karen woke up from her coma 10 days later, she wasn't able to identify him.

So after less than a month, he decided it was time to strike again.

After midnight on February 1st, 1974, Ted went back to the same neighborhood where he'd nearly killed Karen Sparks.

He ended up only a couple minutes away from her house, outside another basement apartment.

This one belonged to 21-year-old Linda Ann Healy, a senior at Washington University.

Linda had gone out with some friends to a popular college bar called Dante's.
