MILWAUKEE (CBS 58) -- CBS 58 has obtained new information about threatening messages that forced Pius XI High School to close for more than a week. 

Monday, Nov. 4, a vandal painted graffiti on one of the entrances and for the first time we're seeing what they painted on the front of the building.

Painted on the doors in white paint are the words "murder kids." 

On the sidewalk in front of the entrance is painted, "I'm bringing a gun and killing everyone."

The messages forced Pius to cancel in-person learning for the rest of the week.

Students returned to class on Tuesday, Nov. 12, and must now go through metal detectors. Armed security will also be on school grounds. 

The suspect was seen on security video with a bike and orange knit mask.
