Complete story — includes the ending
Two murder victims' remains are found illicitly burned alive in a crematorium, including PI Fred Kirby, whose numerous restraining orders cause Sherlock to examine a 1987 shooting spree upon new citizens at their swearing-in ceremony. Virginia Spivey organizes a memorial, but Kirby secretly swapped bloodstained Constitution pamphlets, to have a lab assistant perform DNA tests, seeking a paternity match to Carter Gibson, who's convinced the shooter was not his father. Sherlock realizes Kirby and Carter were killed by blows from a ball-shaped award Carter received for work related to his Charcot–Marie–Tooth disease. Virginia's son Houston is called to the Precinct: Carter had announced evidence that he was not the son of the courthouse shooter, but it's also revealed that the Spivey family had CMT. Having CMT jeopardizes Houston's career as a college baseball star pitcher, expected to gain a major league contract. A loud bang that the neighbors heard was caused by Houston who, after killing with the award, threw it the remarkable distance of 245 feet with spot-on accuracy into a metal dumpster, where NYPD finds it covered in the blood of both victims, and having Houston's fingerprints.
