As Millcreek Police Chief Carter Mook said, the complicated incident involving a big law enforcement and fire department response Tuesday afternoon all started with a phone call about an unwanted family member in a house at 1045 East Gore Road. "The individual who called us for help encountered a family member in the house that was not wanted there."

Sources tell us the report was from a younger male family member.  The unwanted person is now identified at 26-year-old Keegan Baker.

What may have seemed like a routine Millcreek Police call quickly escalated and those in the neighborhood saw smoke and heard lots of gunfire. 

Trooper Cindy Schick, community and public information officer for state police said. "The officers on scene requested additional units for a barricaded male inside the residence and also a house fire."

Additional Millcreek police officers and Pennsylvania State Police officers arrived to help, and that's when the hail of gunfire began. "The male suspect appeared in a doorway of the front entrance of the residence and began firing at officers," Trooper Schick said. "Officers returned fire striking the suspect multiple times."

The charges against Keegan Baker are many, including felony counts of attempted homicide, attempted murder and assault on law enforcement, multiple counts of aggravated assault, arson and also burglary, for entering a house where he was not wanted.

Firefighters who had to hide behind their trucks at first, collaborated with Millcreek's SWAT team.  They were able to pump water from one of their trucks through the armored SWAT vehicle, which could safely move right up to the home and make the initial attack on the fire from the outside.

Authorities aren't saying yet how many Millcreek and Pennsylvania State Police officers fired their service weapons in the exchange with the suspect, or how many shots the suspect may have fired but he was hit multiple times.

At last word the suspect was in critical but stable condition after undergoing surgery at UPMC Hamot.

Erie County District Attorney Beth Hirz confirmed that a state police major case team from Butler in Troop D is now the leading the criminal investigation, with a parallel investigation underway by the Erie County detective bureau.
