Police describe the slaying as a "random and heinous" killing

ROCHESTER — Law enforcement officials say an Arizona woman has been charged with murder in the shooting death of a woman in Brockport.

According to investigators, Holly Marie Collino, 31, of Arizona was arrested Monday night for the murder of Megan Dix last Friday.

Police say Dix was eating lunch Friday afternoon in a parking lot on South Avenue, while on break from her job at Lowe's, when Collino shot her in the head with a gun. Monroe County Sheriff Patrick O'Flynn said the suspect and victim had no previous relationship and Dix was simply in the wrong place at the wrong time.

"Megan Dix, a 33-year-old young mother and wife, was senselessly murdered in this random and heinous act of violence," O'Flynn said. "As the chief said, this could have been anyone."

Collino was then arrested Monday night after deputies say she pointed a gun at an employee at Sticky Lips in Henrietta.

"Deputies responded to Sticky Lips in Henrietta for an employee who had a gun pointed at her head," said O'Flynn. "The suspect was located at a hallway in the Holiday Inn on Jefferson Road. After a brief struggle, the suspect was taken into custody."

Brockport Police Chief Dan Varrenti says Collino lives in Arizona now, but lived in Brockport between 2011 and 2014.

Dix's stunned family has been pulling together and remembering a woman they say was selfless, donating her time to raise funds for local charities and donating her hair to Locks of Love for cancer patients.

"She'd always make her rounds, going to visit everybody, always giving to everybody else, never asking for anything in return," said her brother, Bill Duncanson. "And that's what's really bothering us, you know."
