Emergency crews responded around 7:50 p.m. after callers reported multiple people shot inside the home. When officers and paramedics arrived, they found all four victims dead at the scene.

At the outset of the investigation, authorities identified the victims only as an adult man and woman thought to be in their mid-to-late 30s, along with two young children.

Officials initially estimated one child to be between 5 and 7 years old and the other to be a 4-month-old infant, but the medical examiner later revised their ages.
