Florida Electrician Convicted of Murdering Three Co-Workers in Baseball Bat and Knife Rampage

Shaun Runyon beat his supervisor until 'he saw brain matter' in a calculated attack that left three dead.

A jury in Polk County, Florida, has convicted Shaun Runyon, 44, of three counts of first-degree murder following a brutal workplace rampage in October 2021. Runyon, an electrician, used a baseball bat and a knife to kill three co-workers, including his supervisor, in an attack described by law enforcement as a "cold-blooded, calculated" act of violence. The verdict brings a tragic end to a case that shocked the local community and highlighted the devastating impact of workplace disputes turning lethal.

Background

The crimes occurred while Runyon and his colleagues were working on a contract job for Publix supermarket company for J&B Electric, a Pennsylvania-based firm owned by Runyon’s half-brother. The incident began during the early morning hours of Oct. 2, 2021, when Runyon and his supervisor, 41-year-old Kevin Lanusse, got into a scuffle over a workplace incident. After punching Lanusse, Runyon left the worksite in a rage but returned hours later with a plan to kill.

Runyon drove approximately 70 miles to Tampa International Airport, where he abandoned his work vehicle. He then rented a car and stopped at a nearby Target store, where he purchased a baseball bat. A knife was already in his possession. He returned to a house rented by the company where seven people were staying, entering through the back door and adjusting a security camera that had captured him, according to an arrest affidavit.

The Charges

Polk County Sheriff Grady Judd described Runyon as a "murdering beast" who planned the attack in great detail. The defendant attacked four of the seven residents in the house. The first victim, 41-year-old Gregory Dolezal, was beaten to death while sleeping. The second victim, supervisor Kevin Lanusse, was hospitalized but died later that same day. The third victim, 46-year-old Dewlon "Dew" Donell, was found dead on the front porch.

Runyon was convicted of three counts of first-degree murder and one count of attempted second-degree murder. A fourth victim was attacked with the bat but survived. A family of three, including a then-7-year-old child, escaped unharmed. In his confession, Runyon told deputies he beat Lanusse "until he saw brain matter," and stated his intent was to kill all three victims.
