Gun attack at Mexico student party leaves 14 dead

At a Mexico in a high school party gunman entered and they left 14 dead. Three adults and eleven teenagers died and other 20 were injured. They believe they are the drug gangs who did this. The victims were aged in 15 and 20 years old. The gunmen arrived in early Sunday in many cars at a house. The police knows they were looking for someone and they knew he was at the party that day. They shoot outside the property and then they moved inside and killed some of the teenagers trying to escape over a fence. This is bad influence for all the kids. The people who make parties should have more security or at least they should have a phone to try calling the police. The kids can learn from them and be drug dealers with a gang and have many weapons and kill people. The people should call the police when they are doing a party so they can come and check what is happening in every hour.
