"The female caller gave out that address, our dispatcher then heard the female party hollering 'no, no, no,' followed by gunfire. A male caller then got on the phone and said he was going to kill himself," Schwartz said.
A recording of radio chatter provided by RadioReference.com reiterates that the shooter was in contact with the dispatcher before taking his own life.
"Weld County advising that they have an open line into the residence. They had a caller advise that he had shot multiple people inside the house, family members" a Longmont dispatcher radioed at approximately 4:22 a.m.
"I heard shots at 4:13 this morning. Woke me up and my wife," said neighbor George Vibbert, who also said deputies asked him and his wife to stay away from their windows.
"I heard three [shots] then screaming after that," said Joyce Vibbert.
Schwartz said the dead found inside the home were two adult males, 1 adult female and a female of unknown age who is believed to be an adult.
