unfortuanately, a bad coil or plug caused the catalytic comverters to fail. now the good news, catalytic converters are federally mandated to be under warranty for 8 yrs, 80k miles, so if you're under those limits then the cats can be replaced under warranty. And yes, this is fairly common on escapes, i see a couple a month that have done the same thing, can cause all kinds of issues, even had a few blow the EGR valve right off the intake manifold.

Thank You very much. It unfortuanate but it has 110,000 miles on it. Can i get a used set or should i just get news ones. Thanks for your answer.

actually i've never had anyone ask to install used ones, but i would still answer, go with new, but i would shop around a bit, the factory ones from Ford are fairly pricey, go with aftermarket ones. Also, if the repair shop is telling you to replace the coils and so forth again and you ust had them done, they are still covered under new part warranty and should be covered.
