The businesses that reportedly serve as fronts for the Sinaloa Cartel include a water park, and even a daycare center allegedly managed by Mayo's daughter Maria Teresa. The cartel has plenty of money to funnel through these front businesses, since on average it's reportedly pulling in at least $11 billion a year from sale of drugs across the northern border of Mexico – a figure that is thought to be conservative since it doesn't include any sales made elsewhere, and calculated under the assumption that all the drugs seized by authorities on their way to the US makes up roughly half of the total amount.

If El Mayo is captured or killed – or succumbs to the diabetes from which he is believed to suffer – it's unknown what will happen to the cartel he leads or who will inherit his mantle.
