 Polk County Sheriff’s Office Homicide Detectives Arrest Suspect in 9-year-old Cold Case 

On Thursday, August 12, 2010, Sheriff Grady Judd announced the arrest of 50-year-old Dion Alan Kaseta, 4080 Jenkins Road, Chattanooga Tennessee, in the death of a Polk County woman missing for 9 years.

On December 13, 2001, Broward County Sheriff Office detectives notified Polk County Sheriff’s Office Missing Persons detectives about a missing person reported in their county.  Through the investigation, PCSO detectives learned that then 36-year-old, Kimberly Mimmovich, 2931 Buckboard Trail, Lake Wales, was last seen in Polk County during the evening hours of December 8, 2001, at the Midway Lounge on Highway 92 near Lake Alfred.  Mimmovich was with her live-in boyfriend, Dion Kaseta.  She has not been seen alive since (other than what Kaseta has claimed.)

In 2001, Kaseta told detectives that he and Mimmovich had arrived home at approximately 10:15 pm, and gone to bed the evening of December 8th.  Moments later, at approximately 11:30 pm, Kaseta said Mimmovich suggested the couple leave for a beach trip.  Kaseta told detectives he suggested they drive to Deerfield Beach since Kaseta’s sister and husband lived at 1648 4th Street, Deerfield Beach.  (Kaseta’s sister has since divorced and no longer lives in Deerfield.)

Kaseta told detectives he and Mimmovich made several stops along the way before arriving at Deerfield Beach at approximately 6:00 am, December 9, 2001.  Kaseta told detectives that due to the early morning hour, the couple didn’t go directly to his sister’s home, but rather drove to a shopping center parking lot where they argued.  Kaseta told detectives that the argument was resolved; however, Kaseta said Mimmovich was upset by the argument and told him she would like to walk along the beach alone.  Kaseta said Mimmovich got out of the car and he saw her walk toward the beach and never saw her again.  The residence is a short distance from the shopping plaza

Kaseta said he arrived at his sister’s home approximately 30 minutes later, had breakfast with his sister and brother-in-law, and then went fishing.  Kaseta returned from fishing at approximately 2:30 pm.  He then told detectives he returned to the beach at approximately 4:00 pm to look for her, also calling local hospitals.

Kaseta reported Mimmovich missing to the Broward County Sheriff’s Office at 11:00 pm, December 9, 2001.

Kaseta returned to Polk County the morning of December 10, 2001.  Over the following months, investigators continued questioning Kaseta.  He eventually became uncooperative and refused to speak with investigators further.  He moved to Tennessee in 2003.  His last known address there is 4848 Six Mile Road, Maryville, Tennessee.  

In late 2009 Cold Case PCSO detectives met with Mimmovich’s family and re-interviewed all witnesses in the case. Additional witnesses and evidence was uncovered and it was determined that Mimmovich is deceased and was killed by Dion Kaseta.

The case was presented to the Grand Jury late Wednesday, August 11, 2010.  Kaseta was arrested at his place of business, US Xpress, Enterprises, Inc., 4080 Jenkins Road, Chattanooga, at approximately 9:30 am today, Thursday, August 12, 2010.  Kaseta is being held at the Hamilton County Jail. He is charged with Second Degree Murder.  The PCSO is seeking extradition.
