LOUISVILLE, Ky. (WDRB) – The Louisville Metro Police department has cleared a detective who had been accused of giving false testimony to a Jefferson County grand jury in order to obtain a murder indictment against an 18-year-old last year.

Sgt. Scott Beatty was exonerated on a charge of untruthfulness on Sept. 19, according to a letter written by Chief Steve Conrad.

In February, police denied the allegation from Louisville defense attorney Julie Kaelin, and Lt. Todd Kessinger told reporters there would be no investigation of Beatty.

An investigation was launched a week after Kessinger’s comments.

In early February, murder and robbery charges were dismissed against Isaiah Jenkins, who along with Maunyeh Haggard was accused of shooting 31-year-old Andrew C. Key-Roper on Jan. 28, 2015, at the Russell Apartments at the corner of S. 18th Street and Muhammad Ali Boulevard.

Kaelin, who represents Jenkins, said her client had nothing to do with a robbery or murder and was only indicted because of "false, misleading and calculated" testimony from Beatty, according to a motion she filed in February, while the case was still pending.

In a statement Thursday, Kaelin called the investigation "self-serving," as a finding against Beatty "could affect their ability to get a conviction in other cases which involve his work, and would reflect poorly on (LMPD) as an agency."

 LMPD issued a statement saying Conrad "determined the investigation was thorough and exonerated Sgt. Beatty.

 "We continue to stress that allegations of officer wrong-doing are taken seriously."

Beatty, according to court records, told a grand jury that "both suspects were positively identified through witness statements and photo-packs as being the ones responsible for the victim's death."

"This is simply untrue," Kaelin said in a Feb. 10 motion to Judge Olu Stevens, asking to dismiss the case. "The grand jurors of Jefferson County were led to believe that multiple witnesses indicated Isaiah Jenkins was responsible for the victim's death. This is categorically false."

Prosecutors, according to Kaelin, did not have a single witness who "actually makes such a statement or anything even resembling such an accusation."

Prosecutors and police said Kaelin's motion had nothing to do with the prosecution agreeing to dismiss the case.

Beatty also wrote in a police citation that Jenkins "admitted to participating in a robbery of an individual, where an additional victim was shot and killed," Kaelin wrote. "This is absolutely false."

Kaelin called other testimony "absolutely fiction invented by Detective Beatty."

Kaelin claimed every witness involved identified Haggard as the shooter. One witness identified Jenkins as being present but was "just sitting there," she wrote in April.

"The police are not allowed to mislead a Grand Jury or Circuit Court judge, both of which occurred in this case," Kaelin said in her motion.

In her statement Thursday, Kaelin said that "anyone who looked at the actual evidence in this case and compared it to Sergeant Beatty's testimony to the Grand Jury would see that the testimony was, at best, misleading.

"By exonerating this behavior, LMPD just gave a green light to any officer who wants to get an indictment by whatever means necessary, including illegal activity. It is a blight on the majority of officers who perform their duties faithfully and without violating Standard Operating Procedures or common decency, and it is harmful to our notions of justice and fair treatment under the law. This is a perfect example of why we cannot and should not trust LMPD to police their own."
