WACO -- Earlier this week 53-year-old Carol Allen and 54-year-old William Wareham, both of Elm Mott, were arrested for hosting unlicensed horse races.
Two weeks before that 42-year-old Marcos Ibanez and 60-year-old Nicholas Jaimes, both of Waco were arrested for a similar incident in Axtell.
"The trend has been an upbeat trend all across Texas," said State Trooper D.L. Wilson.
Unlicensed horse racing is more than placing illegal bets.
"It's unfortunate that probably some of the horses, there's been some alleged violence to the horses. There's going to be drug activity at the scene," said Wilson.
An undercover agent we spoke with said it's typical for horses to be injected with performance-enhancing drugs before they race.
That's just one reason why this offense is so severe.
"It's when the organizer knows about the betting or should be aware of the betting that's going on at, if you want to call it a bush track -- which is not a certified track -- that's where the problem comes into and that's a 3rd-degree felony in the state of Texas," said Wilson.
Officials say there are several cases across the state they are currently working on.
"We just want to get the word out to the organizations that we're not going to have that in the state of Texas," said Wilson.
