The yogurt shop murders have been repeatedly described as the day Austin lost its innocence.

My sister was very social, energetic.

She was really into fitness and fashion and, you know, had fantasies of modeling and doing lots of different things.

The youngest of the girls was 13-year-old Amy Ayers, still an eighth grader.

And like her parents and big brother Sean, little Amy was a rancher at heart.

So in December 1991, it was a cool evening.

Of course, the city was getting into the holiday spirit at that time.

And they have ended too soon.

Let perpetual light shine upon them.

There were hundreds of people at the funerals of these girls.

Kids.

So there began this outpouring of tips to the Austin Police Department, quite literally thousands of tips from people who called in.

There was this all-out effort by the Austin community to help solve this crime.

It takes only eight days for one of those tips to produce the first solid lead.

detectives follow that tip to a shopping mall less than half a mile from the yogurt shop and to a 15-year-old teenager named Maurice Pierce.

Different individuals had seen Maurice Pierce with a .22 firearm, that they had been bragging to other people about being at the yogurt shop.

2020 is partnering with Vibes Open Ear Wireless Headphones.

That's V-Y-B-Z.

If you listen to a lot of true crime, you probably like to listen with a good pair of headphones.

But it can be tricky to find a pair that provides great sound quality that's not too immersive.
