Darkness

Ninety-six minutes after the shooting began, the sniper is dead. Everyone nearby converges on campus. Law enforcement and journalists work to identify the dead. Hospitals struggle with the influx of patients. Friends and families mourn their loved ones.

More law enforcement officers swarm campus and join the efforts to stop the shooter. In the tower, a chaotic situation unfolds as a handful of officers and civilians make their way to the observation deck and exchange fire with the sniper.

A police officer assigned to divert traffic from the campus area decides to head into the action. The bookstore employee heads toward the tower and teams up with law enforcement. Together, they hatch a plan to stop the sniper. 

The shooting continues along The Drag, a nearby street full of shops and restaurants. An employee of the university bookstore helps a wounded boy. More people join the rescue efforts. Students eating lunch and shopping take cover or run to safety. Police officers, students, and others get their guns and begin firing back at the sniper.  

The sniper opens fire on the University of Texas campus and the surrounding area. He shoots a pregnant woman, leaving her on hot concrete in the middle of the gunfire. A local radio reporter heads to the scene. Students in a Shakespeare class watch out the window as a police officer is shot. 

It’s August 1, 1966, a hot summer day in Austin, Texas. Not that many people are on the University of Texas campus, except the students enrolled in summer classes. As Monday morning classes start, a 25-year-old former Marine has just killed his wife and mother. He packs the trunk of his car with seven guns and enough supplies to last him days. Then he drives to campus.

On August 1, 1966, a sniper climbed the steps of the University of Texas at Austin’s 27-story tower. Seventeen people were killed and more than 30 others were injured. Fifty-six years later, mass shootings make headlines nearly every week. And the University of Texas tower looms over campus, a reminder of one of the first mass school shootings in United States history that has long been forgotten. In season four of “Darkness,” host Sara Kinney walks through the day of the University of Texas Tower shooting and outlines its legacy among the decades-long epidemic of gun violence in schools. Hear from survivors, heroes and family members about their day in 1966, their lives since then and the state of gun control today.

As the bloody year of 1885 draws to a close and 1886 begins, the police are no closer to solving the vicious crimes that rattled Austin. Even more than a century later, no one knows for sure who killed these women or why. This episode explores the various theories, from the effects of the moon to the possibility that Jack the Ripper started in Texas.

Austin’s city leaders begin to panic amid the bloodshed and bring in outside detectives to help the city’s underperforming police force. Although six Black women have been killed in less than a year, the city and the nation show much deeper concern when two white women are killed in just one night. The mayor, governor, the media and the Black and white communities desperately search for the killer … or killers.

A few months after the death of the first victim, another Black woman working as a servant in Austin is killed. And then another. With three murder victims and a clear pattern, modern officials would know that a serial killer is likely behind the attacks. With few forensic tools at their disposal, Austin’s small and racist police force rounds up Austin’s Black men. The killings don’t stop.

As the capital of Texas celebrates the coming of a new year with exuberance, a dark shadow eclipses the city as an unknown killer stalks the streets. A Black woman working as a servant to a rich white Austinite is murdered, and her boyfriend barely survives. In a city rife with violence, the brutality of the killing shakes up its citizens. And the terror has only just begun.

Law enforcement officers close in on the cult leaders in Mexico City as fear spreads in the communities along the border. As they learn all of the horrible details of the cult’s activities, they turn to their religious faith and to superstition. Thousands gather to celebrate the life of Mark Kilroy, a college student who was so much more than just a headline in a story about a missing person.

A mysterious young woman taking college courses in South Texas befriends a charismatic Cuban American. The two of them work their way into a drug gang in Mexico. In the aftermath of finding the bodies on a ranch, investigators seek the couple. They are focusing on Aldolfo Constanzo, the Cuban American who they believe is the cult’s leader. He keeps slipping out of their grasp.

The bodies unearthed at a Mexican ranch and the people who buried them lead investigators to believe there’s something deeply sinister going on. While tabloids publish screaming headlines feeding into the “satanic panic” and the border communities fear who has been living alongside them, Mark Kilroy’s family offers forgiveness.

Across the border from Matamoros, community members and law enforcement join Mark Kilroy’s friends and family in a desperate search. The friends go on the popular TV crime show, “America’s Most Wanted,'' and Mark’s father pleads on TV for anyone to come forward with information. Police set up road checkpoints, and a car blows right through it. The driver thinks he has powers that make him invisible to law enforcement. Police follow him to a ranch in Mexico … ending the search.
