MUNROE FALLS, Ohio -- The Kent police officer who fatally shot her ex-boyfriend who broke into her home and attacked her early Thursday had an exemplary work record, according to her personnel file.

Sarah Berkey, 30, exceeded expectations of her supervisors in nearly all of the categories on her last three performance reviews dating back to 2011. She had no disciplinary actions taken against her, according to the file.

She had several commendations from superiors for work she performed as a patrol officer and was highly regarded in her new position as the school resource officer at Kent Roosevelt High School.

"I have received a number of positive comments from school staff regarding Sarah's handling of her current duties," Capt. Paul Canfield wrote in Berkey's latest performance review.

Berkey fatally shot her ex-boyfriend, Adam Jovicic, a former corrections officer at the Summit County Juvenile Detention Facility. Investigators noted they believe Jovicic, 29, was drunk when he broke into her Hiwood Avenue home and attacked Berkey.

Munroe Falls Mayor Frank Larson said Friday that they have asked the Summit County Prosecutors Office to review their investigation.

The prosecutors will eventually determine if the shooting was justified or whether Berkey will face criminal charges. Larson gave no new information about the investigation or circumstances surrounding the shooting. He believes that Berkey acted appropriately.

"She did what she had to do," Larson said. "Everyone has a right to defend themselves. No one has a right to attack another person. You can only imagine what she's going through."

Sgt. Bob Post said officers recovered a gun from the home but wouldn't say if it belonged to Berkey or Jovicic. Larson said he didn't know if Jovicic was armed when he broke into the home.

Berkey told a 911 dispatcher that Jovicic attacked her before she shot him. Berkey was knocked unconscious and suffered other minor injuries, according to a Munroe Falls police report says.

Larson said Friday that officers were unable to find which house the 911 call was coming from because Berkey called from a cellphone. It took about five minutes from when the call went through to when officers arrive.d

Two officers were in Berkey's driveway when she fired the fatal shots, a police report says.

Jovicic has a past conviction for attacking a woman in 2013.

Berkey is on paid administrative leave from Kent police, where she earned praise for perfect attendance for 2010 and 2011.

She was cited as being one of several officers whose work ended led to the arrest and conviction of five people in a home invasion on South Lincoln Street.

Berkey was also given an official commendation for her work in a murder investigation and ensuing trials of Adrian Barker and Ronald Kelly. Both were convicted of killing Kent State student Christopher Kernich in November 2009.

"Your dedicated work ethic and professional performance demonstrated from your initial response to unfold through the end of the second Murder trial was exemplary," wrote then-Police Chief James Peach. "Your performance and testimony proved to be critical components for the successful conviction of both murder suspects."
