SPOKANE, Wash. -- Caroline Francis was driving home from the gym last week when three young men pulled up next to her acting like they needed directions. When she tried to help them, they threw urine in her face.

Around 7:30 p.m. last Tuesday, Francis was headed home after working out at the YMCA . She pulled to a stop at the light at Lincoln and Boone when a large white van pulled up next to her.

"There was a guy sitting there doing this, 'Roll down your window,'" Francis said, motioning. "He was asking me for directions where some road was."

From what Francis thought was the safety of her own car, she gave the three men in a van directions. But the three kept asking questions, she said.

"I should have known something was up because he was inquiring a lot," she said.

As soon as the light turned green, the men drenched Francis with a 20-ounce water bottle filled with urine. At first, Francis said she didn't know what had hit her.

"I know this is really gross, but I thought it was water. And then I could smell it and it was all over me and I was freaking out, shaking," Francis said. "It got all over me -- in my eye, in my mouth, all over my car."

Francis is trying to forget the stench of the incident, but she said it's one of the men's faces that's been the hardest to forget.

"He leaned out the window and threw it at me, and then came out even farther so that his waist was out the window. And he just had to get every last drop on my face, and he had the meanest look on his face. I won't forget that look. It was so malicious," she said.

After a long shower, Francis alerted police, who are now investigating. No arrests have been made in the case.
