DSP says the preliminary investigation revealed that the robbery suspect had been to the home earlier in the day on December 16, then returned to the home around 6:00 p.m. that day with three additional suspects. The four men forced their way into the home, with one displaying a firearm. Once inside, police say the suspects demanded money and other items. One of the suspects struck the victim on the top of his head, then all four suspects fled the home on foot. The victim sustained minor injuries following the robbery.
