Still, her mother's grief was raw.
Nazario, a 40-year-old single mom and strike force officer, died after a stolen SUV plowed into her police cruiser at 39th and Wallace Streets.
At the memorial, candles were lighted at 9:41 p.m., the precise moment Nazario passed away.
Her longtime partner, Officer Terry Tull, drove the cruiser that night. He suffered a broken hip, ribs, and heart.
"This is my first time back here. It's rough. It just brought back a flood of different thoughts, how that whole day went before that moment. I just try to remember the moments after that, it's just all a blur," Tull said.
Her now 16-year-old daughter Jasmine spoke to the 200 or so officers that came out to remember.
"It doesn't even feel like a year. I want to thank everyone who came out for support for my family," Jasmine said holding back tears.
As Isabel Nazario's police family left, they vowed to keep her memory and her commitment to protecting people in Philadelphia's community alive.
