Zombies escape and are attacking

Who is responsible for hacking the system?

Just in, Zombie HQ is under attack by flesh eating corpses (commonly known as zombies
). Someone hacked the system to get the zombies that have life like abilities. Becky reported that they are currently trapped in a room and trying to find a way out, and one of there team mates went crazy and killed the doctor that was originally trying to save them. It is also reported that there is also a deranged clown on the loose in this facility. But who could be doing this madness? Could it be another doctor that is jealous of the experiment? Kids that are playing a joke? Or just a glitch in the system? More news is to come ahead.
