WESTON, Mo. -- Police are searching for the magazine salesman who tried to rape a teenage baby sitter.

The baby sitter was looking after an 8-month-old girl at a home in the 800 block of Ashley Street. She said there was a salesman who knocked at the door; she told him she wasn't interested.

About an hour later, a different salesman came to the door, but he wouldn't take no for an answer.

"I've always had my door unlocked. Now I can't trust anybody," said Lacey, the mother of the 8-month-old. She didn't want her last name used.

Lacey said she wasn't worried about leaving her baby in the care of Heaven, a teenage baby sitter. And Heaven said she hadn't been worried about opening the door to a pimple-faced magazine salesman.

"He didn't have any papers or anything like that. I said, 'I'm not interested.' I went to close the door and he slammed it back open," Heaven said.

The teen said the man forced his way through the doorway into the home.

"We wrestled on the ground for a little bit. I got up again, he kept pushing me into the corner," Heaven said. "I'm sure his intentions were to rape me -- he had my pants down, he had his pants down, he tore my underwear."

She said she never let go of the baby during the attack.

And for some reason, the man decided to stop.

"I was screaming my head off, the baby was screaming, the dog was barking -- I don't know what startled him, but all of the sudden he got up and ran out of the house," Heaven said.

She said she doesn't feel comfortable baby-sitting at the home anymore.

And Lacey said she won't feel comfortable until the attacker is arrested.

"I'm hoping they find him, put him away," Lacey said.

Weston police said they're investigating the assault and attempted rape.

The teen described her attacker as in his late teens, thin, about 5 feet 6 inches tall and with bad acne.
