Two people were found dead in a Jacksonville home on October 24, 2017. Sharon Lamb, 55, and her brother Michael Lamb, 52, were discovered at their Argyle Forest residence and the Jacksonville Sheriff’s Office is treating both deaths as a double homicide. No signs of forced entry were reported, yet investigators describe the deaths as foul play.

Sharon’s son, Andrew Lamb, was arrested the next day on unrelated drug charges; police say he previously had violent altercations with his mother, including a known physical assault. Neighbors, however, described Andrew as a caring son who checked on his mother and expressed doubt about his involvement. Investigators are also looking into two vehicles of interest, a red Ford Escort and a green Ford Explorer.

The case remains unsolved. If anyone has information about the killings, the vehicles, or the family’s movements around October 24, 2017, please share what is known with authorities.
