Monday began a period of mourning for fallen Philadelphia Police Officer Shane Seiber.

Officer Seiber’s partner, Officer Hector Rodriguez, was also shot during that ambush.

Philadelphia Police Commissioner Kevin Bethel said his prognosis is positive, telling Action News that Officer Rodriguez is getting out of bed, walking and talking.

Commissioner Bethel said Seiber, who grew up in Bucks County, always wanted to be a police officer.

He was known affectionately by the nickname “Colgate” for his infectious smile.

“Everyone talks about his smile,” Bethel explained. “From the time he was a child, I don’t think he ever stopped smiling.”

Seiber was also a veteran who served two tours in Iraq as a member of the Air Force.

“Our goal here today is to show his family that he was part of something special,” Bethel said. “Our job is to never stop caring for their family. They have a three-year-old and seven-year-old.”
