Investigators said there were six people inside the mobile home, but no one was hit.
Police said they received conflicting stories and suspect descriptions from witnesses.
Investigators said a short time after the shots were fired, officers also responded one row over to a report of someone breaking out the window of a pickup truck.
Police officials believe the two incidents are connected.
Later in the night, police arrested these three people, Jose Lopez, Jesus Lopez and Daniel Rios Sanchez in connection to the shooting. They were booked into the Fayette County Detention Center on wanton endangerment charges.
