MARION COUNTY, Fla. – A man and a woman from Marion County who murdered a government informant in an attempt to cover up their drug operation will now spend the rest of their lives behind bars.

The Department of Justice on Thursday announced the sentencing for David Fey, 57, and Shari Gunter, 58, who were found guilty in December in the murder of the 31-year-old victim, who was only identified as K.B. by investigators. Prosecutors said K.B. was a mother of three children.

Fey and Gunter lived together in a Summerfield home, where they also sold methamphetamine. Prosecutors said the victim was a customer of the pair but had agreed to cooperate with law enforcement.

The victim conducted a controlled buy of meth from Fey and Gunter in January 2016. However, Gunter and Fey became aware that the victim was working with investigators.

In April 2016, Fey and Gunter prepared a syringe with a fatal amount of meth and fentanyl for the victim. After the woman injected herself, prosecutors said she immediately collapsed.

Fey and Gunter dragged the woman outside their home, kicked her in the head and gave her a second lethal dose of meth and fentanyl. The pair then drove the woman to a cemetery and attempted to make her death look like an accidental overdose.

“On April 6, 2016, K.B. was found deceased in her parked vehicle near a cemetery in Oxford, Florida, the victim of an apparent drug overdose. Upon further investigation by local, state, and federal agencies, it was determined that K.B.’s death was not accidental, but that she died from homicide caused by the intentional injection of fentanyl and methamphetamine,” a news release read.

Fey and Gunter were both found guilty of distribution of meth, conspiracy to murder a government witness, murder of a government witness and conspiracy to distribute meth and fentanyl causing death.

Fey also pleaded guilty to seven additional counts of distributing meth.
