The Phoenix Lights | Marks Unexplained World Podcast Extra

On the 13th of March 1997, Between the hours of 7:30pm and 10:30pm lights of varying descriptions were seen by thousands of people, in a space of about 300 miles (480 km), from the Nevada line, through Phoenix, to the edge of Tucson.

There were two distinct events involved in the incident: a triangular formation of lights seen to pass over the state and a series of stationary lights seen in the Phoenix area.

The United States Air Force identified the second group of lights as flares dropped by an A-10 Warthog aircraft that was on training exercises at the Barry Goldwater Range in southwest Arizona. Witnesses claimed to have observed a huge square-shaped UFO containing five spherical lights or possibly light-emitting engines. The governor of Arizona, Fife Symington, years later, said he witnessed this incident, describing the object as being "otherworldly."

The 1991 Austin yogurt shop killings are an unsolved quadruple homicide that took place at an I Can't Believe It's Yogurt! shop in Austin, Texas, United States on Friday, December 6, 1991.

The victims were four teenage girls: 13-year-old Amy Ayers, 17-year-old Eliza Thomas, 17-year-old Jennifer Harbison, and Jennifer's 15-year-old sister Sarah. Jennifer and Eliza were the shop employees, while Sarah and her friend Amy were in the shop to get a ride home with Jennifer after it closed at 11:00 pm.

A Y-chromosome match for the perpetrator DNA has been found in a research database of the Federal Bureau of Investigation (FBI) but it has declined to reveal the identity of the man by the law of anonymity for donors, and because thousands of men could bear this fragment of DNA, which is unable to identify individuals.
