VARDEN - An incident report sheds further light on the accidental shooting at Western Wayne High School.

School police officer Paul Semler had been suspended last week after his Glock .45 caliber handgun discharged a round while he was cleaning it in his office during school hours.

The report stresses that Wayne County detectives determined the firearm belonged to Semler.

According to a copy of the incident report provided Friday to The Wayne Independent:

Vice Principal Paul Gregorski went into Semler's office on the morning of Feb. 18. Gregorski told the officer that he had purchased a holster and asked Semler what the process is for using a weapon at a shooting range.

The discussion was "very brief" and Gregorski left the office. Later, the vice principal walked by Semler's office and the officer had taken out the gun and was cleaning it.

Semler showed Gregorski how the magazine went in and out.

"As he demonstrated, he pointed the gun down toward the desk and it went off," Gregorski told Superintendent Clayton LaCoe, according to the report. "My ears were ringing. (Semler) said I cannot believe that happened."

LaCoe asked Gregorski, "Was it your interest in recreational firearms use that had you in that office?"

The vice principal responded, "Just briefly, yes."

Semler owns a full-size .45 caliber Glock 21 handgun loaded with .45 caliber full-metal jacketed ammunition.

He had purchased the handgun about 2 1/2 months prior to the incident and had never cleaned it.

Semler cleaned the gun with spray lubricant and rags, then reassembled it and inserted a loaded magazine.

"However, he does not remember chambering a round into the barrel," the report states.

Semler remembered that Gregorski had also recently purchased a Glock .45 caliber handgun, so he called the vice principal into his office to show him how to clean it.

Gregorski went to the office, standing "in or just inside of the doorway."

Semler stood up and removed the magazine from his handgun. "He then pointed and actually placed the muzzle of the handgun against the calender on his desk," the report states.

"His intention was to pull the trigger to release the slide, push the end of the slide against the desk to line up the slide with the slide lock, and then remove the slide (pulling the trigger is a necessary step in the disassembly process of Glock handguns)," the report states.

When Semler pulled the trigger the handgun discharged one round. The round traveled through the desk and struck the carpeted cement floor.

The top page of the desk calendar was charred and covered in gun powder residue and debris.

Semler completed a written statement that was consistent with his verbal statement, according to the report.

Wayne County detectives stated in the report that at no time did they discover any information that would indicate the handgun that Semler used belonged to someone else.

In response to the incident, multiple school directors have said they intent to revise school policy restricting an officer from cleaning a weapon during school hours.

Director A.J. Gaudenzi said he expects a revised policy to be in place by April, noting that the matter needs to be addressed expeditiously.

Director Don McDonough said a school police officer should not have a weapon out of a holster unless it is to protect himself or others. Cleaning of the weapon should be done off campus, McDonough said.

Gaudenzi agreed, saying the officers should only have their weapons out of their holsters during an "eminent threat."

Gaudenzi also said the safety of the students, employees and community is paramount.

District Attorney Janine Edwards determined after the investigation that no charges would be filed against Semler. It's unclear if the officer has returned to work, since the superintendent said the matter is a personnel issue.
