An Iowa woman has pleaded not guilty to murder charges in connection with the 2011 killing of real estate agent Ashley Okland, according to court proceedings.

Kristin Ramsey is accused of shooting Okland in 2011, a case that remained unsolved for over a decade before charges were filed. The victim was a real estate agent working in Iowa at the time of her death.

Recently released court documents include new witness testimony regarding the incident. According to these documents, a witness reportedly observed Ramsey fleeing the scene in an erratic manner following the shooting and allegedly failing to call 911.

The case represents a significant development in what had been a cold case investigation spanning more than 13 years. Okland's death occurred in 2011, and the case had gone without resolution until recent legal proceedings brought charges against Ramsey.

The witness account detailed in the court filings provides investigators with what they describe as new evidence in the long-dormant case. The testimony specifically addresses Ramsey's alleged actions immediately following the shooting incident.

Ramsey's not guilty plea sets the stage for further legal proceedings as the case moves through the court system. The investigation into Okland's death had remained open since 2011 before leading to the current charges.
