2016 Kansas–Missouri murder spree

Between March 7 and March 8, 2016, five men were killed in two shootings roughly 170 miles apart in Kansas City, Kansas, and unincorporated Montgomery County, Missouri. On the night of March 7, four men — Jeremy Waters, 36; Michael Capps, 41; Clint Harter, 27; and Austin Harter, 29 — were shot to death in Kansas City, Kansas, with an AK-47-style rifle. One victim managed to call police about the shooting before dying.

On the morning of March 8, 49-year-old Randy J. Nordman was shot to death in Montgomery County, Missouri. A truck believed to have been driven by the suspect was later found abandoned about five miles away along Interstate 70, prompting a large-scale manhunt involving two police helicopters and at least one SWAT team.

On March 9, police in New Florence, Missouri, responded to a report of a man pulling a firearm on a civilian at a gas station. At 12:18 a.m., Pablo Antonio Serrano-Vitorino, 40 — who had lived next door to the four Kansas victims — was found armed with a Kalashnikov rifle at a muddy hillside along Interstate 70 and was arrested by Missouri State Highway Patrol Sergeants Primm and McGinnis without shots being fired. He was charged with four counts of first-degree murder in Kansas and jailed in Montgomery County, Missouri, with bail set at $2 million. The day after his arrest, he attempted suicide by cutting himself with a safety razor and was hospitalized in stable condition.

On June 1, 2016, Serrano-Vitorino pleaded not guilty to the Missouri killing of Randy Nordman; prosecutors sought the death penalty in that case. In September 2016, a Montgomery County judge transferred the Missouri case to St. Louis for trial.

Serrano-Vitorino, a Mexican national, had previously served a two-year sentence in a California prison for making a terrorist threat and was deported from the United States in April 2004, but later reentered the country illegally. Despite subsequent legal issues, including a battery conviction in the summer of 2015, he had avoided deportation prior to the 2016 killings.

On April 9, 2019, Serrano-Vitorino was found alone and unresponsive in his cell, having hanged himself. He was taken to a hospital, where he was later pronounced dead, before the Missouri case could conclude at trial.
