LEHIGH ACRES, Fla. - A teen boy in Lehigh acres was arrested Wednesday for trespassing on Lehigh Senior High School Property. Deputies searched him and found a gun in his belt.

Deputies say 15-year-old David Rodriguez snuck inside the school after being told to stay off school grounds by a school resource officer. Deputies caught him exiting the school building after the final bell rang for the day. According to reports, he was immediately arrested for trespassing and that's when Deputies found the gun.

The teen's mother, Ivonne Rodriguez tells WINK news she does not know where the gun came from. " We don't understand because I check his room every day, he doesn't have a place to hide it...I don't know," said Rodriguez.

We asked Rodriguez if her son may be capable of harming someone. "No, no...we're Christians," said Rodriguez. Investigators have not said what, if any motives existed when Rodriguez went into the school. However, in the arrest report, it says the resource officer asked another juvenile, who was with Rodriguez off of school property, if he thought Rodriguez was looking for trouble. The other teen replied, "You should probably check him out."

Rodriguez is being held in the Lee County Juvenile Assessment Center.

The Lee County School District says an automated phone message was sent out to parents Wednesday, notifying them of the situation. District spokesman Joe Donzelli says security measures will be reviewed and adjusted if need be as a matter of protocol.
