Keynen M. Guider Jr., 26, of Harrisburg was found shot and unresponsive in his vehicle in the 1900 block of Brookwood Street on December 31, 2017. He was transported to Harrisburg Hospital and pronounced dead there.

Authorities arrested 31-year-old Calvin McKinney of Harrisburg and charged him with Guider’s murder and attempted murder. Prosecutors say McKinney allegedly shot Guider on December 29, 2017, and again two days later, the second shooting proving fatal. During the first trial the jury convicted McKinney of attempted murder but was hung on the murder charge, producing a mistrial; McKinney received a 10–20 year sentence on the attempted murder conviction. Reports from the trial also allege perjury by McKinney.

What can anyone who knew Keynen or saw activity around Brookwood Street in late December 2017 add to help the investigation?
