Katty Gomez was preparing for her 15th birthday party at her Baton Rouge apartment Saturday afternoon when three sheriff’s deputies from Los Angeles strolled up to the front door.

Katty grew up in Los Angeles, and the three deputies she has come to regard as her guardian angels were in Louisiana to surprise her on her quinceañera, some eight years after the fatal shooting of Katty’s mother brought them together.

They have remained in touch ever since that shooting.

As Katty stepped outside the apartment in a formal teal gown and saw the deputies approaching, she teared up and put a hand to her mouth. After they hugged, they presented Katty with an array of gifts: an iPhone, laptop, Tiffany & Co. necklace and a $1,000 gift from the City Council in Carson, where the 2006 shooting took place.
