Investigators have identified the man who opened fire on City of Erie, injuring a patrol sergeant who remains hospitalized.

Patrick Gleba, 27, faces charges including attempted homicide, attempted homicide of a law enforcement office and aggravated assault of a law enforcement officer.

Police were called for gunfire just before 5 a.m. Sunday in the 500 block of E. 22nd St.

Multiple officers were searching the area after finding spent rifle casings and broken glass. They established a perimeter and were using the headlights of their patrol vehicles to light up the area when a Gleba opened fire using an AR-15 at several uniformed officers from inside a duplex.

Patrol sergeant David Stucke, 42, was shot once in the leg, went about 40 feet to take cover behind a police vehicle and put on a tourniquet while the other officers returned fire. According to Erie Police Chief, Dan Spizarny, "David began to put on the tourniquet he carries to save others, today it was for him."

Officers took Stucke to UPMC Hamot in a police vehicle, and he underwent emergency surgery. Stucke remains in stable condition but has a long road to recovery, according to City of Erie Police Chief Dan Spizarny.

Gleba, who was wearing a bulletproof vest and was armed with a knife and additional rounds of ammunition, eventually came out of a house and surrendered to officers. He was not injured and taken to the police station.

Stucke wrote a note while in the hospital, saying he's not leaving the streets.

He served in the U.S. Marines and was deployed to Iraq. He is a third-generation police officer. According to Erie Police Chief, Dan Spizarny, "David is a third generation Erie Police officer. His parents are retired from the department. His two uncles are retired. Three police chiefs as was his grandfather."

Pennsylvania State Police in Erie is handling the shooting investigation. Troopers were on the scene throughout the day Sunday. According to Captain Kirk Reese with the Pennsylvania State Police,  "Third party law enforcement agencies are often requested to investigate uses of deadly force by other departments for reasons of transparency. Erie City Police conducted their own parallel investigation into their own policies and procedures surrounding this incident. All of these actions took place under the supervision of the Erie County District Attorney's office."

Anyone with information, photos or video of the incident is asked to call state police at 814-898-1641.

Neighbors surprised

Neighbors and Erie residents who visit the neighborhood often were surprised by Sunday morning's events.

"This time it just gave me goose bumps because he's like, literally right there in the center of everything", said Stephen Herbstritt, an Erie resident.

Herbstritt used to call East 22nd street home, he's moved away, but he still visits the neighborhood to see friends. "He texted me this morning, he was like, I woke up to gunshots, and he was like, there's like, blood on the street. And I was like, really? Are you okay? He was like, yeah,"

Herbstritt returned to the neighborhood to check on his friend after the shooting happened, "I was not even shocked and just worried about other people around because it feels like people with guns and such don't even take in consideration of other people's safety and especially with little ones around this time of day like this."

People who visit and live on these streets said this is a fairly calm and quiet neighborhood, so they were surprised by Sunday morning's shooting. However, they said they were concerned with the violence since so many young children and families live in the homes where they shooting took place.

Neighbors said since they've moved here, there hasn't been too many issues with violence recently, but it's happened in years past.

Herbstritt said while his friend is okay, he's more concerned about the young families who are exposed to the violence. "This is the worst part, because we got little kids and everything and, like that stuff should not be okay around here", said Herbstritt.
