(DALLAS) -- Cell phones are causing headaches again for Texas correctional officials.
Two years ago, after a state lawmaker started receiving threats, apparently from a convict, a sweep of the massive Texas prison system turned up over 100 smuggled cell phones, along with accessories like chargers and batteries. It's now become an issue in county jails, too, after one inmate used his phone to plan his escape and then to go on Facebook once he was out.
Officials are looking at ways to electronically jam cell signals rather than trying to round up all the smuggled devices.
