( CNN ) -- A Wyoming man was charged Friday with four counts of first-degree murder after , authorities say , he shot dead three of his children and another relative inside his home . According to the warrant for his arrest , Everett E. Conant III is also charged with attempted first-degree murder , aggravated battery and possession of a deadly weapon with unlawful intent . Magistrate Scott Cole ordered Conant held with no bond , following his arraignment Friday afternoon in Platte County . In addition to the four dead , law enforcement said that Conant shot and injured an adult woman -- identified in court records as Suzette Ann Conant , the suspect 's wife . Wheatland Police Officer Doug Wiggins wrote in a criminal affidavit that he encountered the woman on the street shortly after 5 p.m. Thursday , soon after he 'd arrived to investigate a report of screaming and shots fired . The woman , who had been shot in the leg and shoulder , identified her husband as the shooter and said her children may have been shot as well , according to the affidavit . She said that Conant was still in the house and armed . Wiggins said he then confronted the suspect through a doorway , at one point observing something black in his hand during the conversation as well as `` what appeared to be a lifeless body of a male juvenile on the couch , surrounded by blood , '' the affidavit said . The suspect -- later identified as Conant -- was coaxed out of the home , unarmed , after about 10 minutes and was arrested `` without incident . '' More officers from Wheatland and the Platte County Sheriff 's Office then arrived and went through the house . There , they found the dead bodies of three minors -- who were born between 1993 and 1999 , according to charging documents , which did not identify them by name or birthdate . Another adult male , 33-year-old Nacuma Roland Conant , was found shot and struggling to survive . Officers began efforts to try to save the man 's life , but he was later pronounced dead at Platte County Memorial Hospital , according to the affidavit from Wiggins . The incident occurred in Wheatland , a town of about 2,400 people that is located about 70 miles north of Cheyenne . Convictions of any of the four first-degree murder charges are punishable , potentially , by the death penalty . CNN 's Greg Botelho contributed to this report .
