Michael D. Siau, a 38-year-old White man, was found dead in a ditch along Plantation Drive near Hot Wells Road in Alexandria, Louisiana. A jogger discovered the body on September 26, 1985, and investigators determined the injuries were the result of a severe beating; authorities treated the death as a homicide and focused on reconstructing where the assault began and why he was left at that location.

The site and condition of the body suggest he may have been dumped or abandoned after the attack.

If anyone knew Michael Siau, his movements that month, or has information about the area around Plantation Drive in late September 1985, please come forward with tips.
