An arrest was made early Friday in connection to the four people found dead in a small Nebraska town on Thursday, according to the Nebraska State Patrol.A press conference is scheduled for 9:30 a.m. CT Friday.The four were found dead in two separate homes in Laurel, a northeast Nebraska town, and authorities said fire was involved at both locations. Authorities believe gunfire also played a role in the deaths.Investigators believe the fire in the 500 block of Elm Street may have started around the same time as the reported explosion in the 200 block of Elm Street. Both are believed to have happened shortly after 3 a.m. Three people were found dead in the second residence and fire crews worked to preserve evidence while putting out the fire, according to Nebraska State Patrol. According to the state patrol, foul play is suspected in the death of the four people at two different crime scenes that are about five blocks apart in Laurel, which is in Cedar County, is home to fewer than 1,000 people, and is about 100 miles northwest of Omaha. Officials are waiting on autopsies for the causes of death."This is a tiny, safe community. We aren't sure if they knew each other, but everyone knows everyone in this community," Cedar County Sheriff Larry Koranda said. "If people see something out of the ordinary, call the state patrol."Shortly after the second fire, a silver sedan, reportedly driven by a Black male, was seen leaving Laurel and may have picked up a passenger before leaving town, according to the Nebraska State Patrol.
