FARMINGTON, CT (WFSB) - A woman is accused of intentionally misleading investigators as they looked into a Farmington murder that happened back in 1998.

Katherine Pires, 50, of East Hartford, faced a judge in Hartford on Monday.

With Pires' arrest, police believe they're closing in on solving the case.

She faces several charges stemming from the case of 26-year-old Agnieszka Ziemlewski, also known as Agnes or Niki. Ziemlewski was shot at close range in Farmington on Sept. 24, 1998. 

Police said Ziemlewski was walking on a trail at the MDC Reservoir property at the time. She was killed 100 feet from the gate at Old Mountain Road.

The police department said it has continuously investigated the case and did not let it go "cold." 

The Farmington Police Department's detective unit said it partnered with the Federal Bureau of Investigation behavioral analysis unit in 2018 and conducted a complete review of the case. 

Police arrested Pires in connection with the investigation. 

She was charged with second-degree hindering prosecution and interfering with an officer. 

“Part of the hindering prosecution statute is she’s rendered criminal assistance to intentionally lead investigators down incorrect paths, we believe to protect one of the persons of interest in this case that she knows," said Lt. Tim McKenzie, Farmington police.

Pires was held on a $250,000 bond before appearing in court on Monday, where it was dropped to $25,000.

"The Farmington Police Department will not rest until justice is achieved and closure is obtained for Agnes’s family," police said in a statement. 

A $50,000 reward is being offered for any information leading to the arrest and conviction of the suspects responsible for Ziemlewski's murder. 

“We’re there," McKenzie said. "We’re close, we know we’re close.”
