Two letters have been discovered in the common area of a southeast Wichita apartment complex. The most recent letter was found Thursday morning and both letters contain threats of violence against Wichita Police.

The author of these notes included bullets as an example of what he would use against officers.

The letters also included details from the shooting of an off-duty police officer outside the Wichita Area Technical College in March. The officer survived because the bullet lodged in his walkie talkie.

"We were thinking quite seriously that the author of this document was going to be our shooter so needless to say we gave this our full one hundred percent attention," Deputy Chief Tom Stoltz said.

By comparing personal details of the letters as well as handwriting, investigators traced the two letters to a 14-year old boy, who admitted to having written them because he was upset with his parents and told police he thought they were funny.

The boy delivers flyers and papers to the apartment complex, which is when he delivered the threatening letters.

Police arrested the 14-year old boy for making criminal threats and said that he is not involved with the shooting of the off-duty officer.

After spending hundreds of hours over the past week trying to track who police thought was the shooting suspect, they are now back at square one, looking for the real suspect.

"We will now have to start back over on this investigation as we stated in the past we need the public's help regarding the solving of this case," Stoltz said.
