Summer Danielle Tennyson, 39, was found dead from a single gunshot wound in her Caledonia, Mississippi, home in the early morning hours of a Tuesday in June 2023. Deputies discovered her after a 911 call reporting an unresponsive person; the coroner estimated the fatal wound occurred early that morning. She was a mother of four and two of her young sons, then aged 4 and 5, were asleep in the house at the time and were left with their mother after the shooting.

Investigators quickly focused on her boyfriend, 36-year-old Phillip Shane House, who was already in custody on unrelated traffic warrants when he became a person of interest. Prosecutors say the couple had argued at a YMCA that night and continued through text messages; a final message sent from his phone pinged near her residence and read Game over. Prosecutors allege House retrieved a gun, returned to Tennyson’s home, and shot her while she slept. His brother reportedly testified that House admitted the killing and threatened him.

Did anyone in the area know the couple or see either of them near the YMCA or Tennyson’s home that night?
