CULPEPER, Va. (WUSA) -- It's been almost three months since a Culpeper Police Officer shot and killed a retired Sunday school teacher in a church school parking lot, yet there are still more questions than answers about what happened the day Patricia Cook was killed.

The investigation is now in the hands of Virginia State Police, a special prosecutor in Fauquier County, and a special investigative grand jury. But many people in Culpeper say the investigation is taking too long.

"I think it's a coverup," said Patricia Wise, a Culpeper resident as she walked past the site of the shooting Tuesday morning.

State Police say the officer, who's name has not been released, was responding to a report of a suspicious person sitting in a car in the Epiphany Catholic School parking lot. When the officer asked 54-year-old Patricia Cook for identification, she rolled up her window catching the officers arm inside, then drove off. Police say she was dragging him down the street when he opened fire. But at least one eye witness says that account is incorrect.

"The window was halfway up. He said stop or I will shoot. I didn't think he was going to do it. But she got the window all the way up and that's when he shot her," said Kris Buchele.

So far, no charges have been filed against the officer. He is still on paid administrative leave pending the outcome of the investigation. The only thing the town spokesman will say is that: ""The investigation is in the hands of a special prosecutor and the state police. Like everyone, we await the results of that investigation."

That response doesn't sit will with James Jennings, a Culpeper resident and retired elementary school teacher.

"Something just doesn't add up. How could this woman, who is a retired homemakers and who was unarmed, how could she be shot to death in a church school parking lot?" asked Jennings.

Last week, Jennings started a "Justice for Patricia Cook" Facebook page. He's also started an online petition requesting that criminal charges be filed against the officer. So far, he's received almost 350 signatures.

"Our primary focus is to ensure that all the details, evidence, and eyewitness accounts are brought out into the open," said Jennings. "This should not be closed-door investigation."

But other people in town, like Wayne Rinker, say Jenning's is causing more harm than good.

"I think people should just be patient and let the judicial system run it's course," said Rinker.

Virginia State Police haven't given any timeframe as to when their investigation will be complete. The special prosecutor in Fauqier County says it will be the end of June at the earliest before the grand jury has reached a decision.
