Authorities say a man fatally shot a relative on Christmas Day in a Black Hawk County home. The Waterloo-Cedar Falls Courier says that the Black Hawk County Sheriff’s deputies responded around 4:30 p.m. after a resident called 911 to report that there had been a shooting between family members. Forty-three-year-old Chad Buck was rushed to a hospital, where he was pronounced dead. Deputies determined that there was an argument before the shooting at Buck’s rural home. Capt. Mark Herbst of the sheriff’s department said in a news release that no further information, including the names of others involved, will be made public at this time pending further investigation and the results of the victim’s autopsy.
