Officials from the Ingham County Sheriff’s Department are asking for assistance in identifying a suspect in their investigation into the murder last month of 69-year-old David Fluke.

Authorities are seeking an individual who may present as either masculine or feminine. They’ve released a composite sketch of the suspect, whom they describe as being white, in their 20s and between five foot eight inches and six foot tall. Officials said when the suspect presents as masculine, the suspect has short blond hair. When presenting as a feminine, the suspect wears a blond, shoulder length wig. They say the suspect drives a black Pontiac car.

“The investigation has revealed that Mr. Fluke had contact with the LGBT community and homeless/transient people in the Lansing area,” a press release from the department reads. “Mr. Fluke used various social media outlets seeking male companionship.”

Ingham County Sheriff authorities were called to Fluke’s apartment Oct. 11. The apartment is located in Holt, Michigan, a postal code identification for a portion of Delhi Charter Township, just south of Lansing. The apartment is in a senior living community.

Det. Brad Delaney, lead investigator on the case, said that officials have one witness who has “only seen the subject dressed as a man,” and another witness who has “only seen the subject dressed as a woman.”

Fluke does have a criminal history in Illinois and Minnesota for improper contact with minors, a google search reveals. Delaney said investigators were aware of his past, and investigated any role that may have played in his murder, but it did not result in any leads.

“I don’t have any concern about what the sexual orientation or the gender identity of the person is, I just want to solve this murder,” Delaney said in an interview in Mason Thursday. “I need help to solve this.”

The department is now offering a reward to anyone who provides information which leads to an arrest and conviction of the person or persons responsible for the crime. Those who may be able to identify the suspect are asked to call Crime Stoppers at 517-483-STOP or a detective at 517-230-3120.
