The case of Howard Unruh

Although it appeared to be a small issue, it was actually a turning point. His life would alter the moment he noticed the missing gate, which had just been installed that day. Now was the time to act, whatever the cost.
After at least two years of planning his retaliation, it was finally time to carry out his original scheme. The six-foot-tall loner, dressed in a brown, tropical worst-head suit, white shirt, and striped bowtie, grabbed his 9mm German Luger and headed outside.
It was approximately 9.20 a.m. on Tuesday, September 6. His mother was out of the way; she had just departed. He had a large collection of guns, so he could have picked any number, but he preferred the Luger. He also reached for a six-inch knife and a tear gas pen with six shells, just in case.
He entered the road after cutting through few side streets. This otherwise calm veteran of World War II is marked on a map created that evening for the Philadelphia Inquirer, which described the shooter as a maniacal man with a deranged mental state.
Although the precise order of events on that date varies from newspaper to newspaper, the outcome is always the same. The silent, slender man was going to write history. In just one episode, he would become the first mass murderer in American history.
