When a fresh-faced, 20-year-old Carole Axford started work at the Clark County Prosecutor’s Office, she used an IBM electric to type court filings.There was a staff of six, including the county prosecutor. The work — typing interviews with trial witnesses, sentencings and other miscellaneous court hearings — was daunting for Axford when it involved murders and rapes.When the prosecutor at the time was preparing for a high-profile murder case, he spared the newcomer the grittiest assignments.“He gave me a witness list (to type) because he thought I was too young” to work other aspects of the case, Axford recalled.That was 50 years ago.Today, you’d be hard-pressed to find anyone more seasoned in their job. Axford, 70, celebrates a half-century with the prosecutor’s office this month and is believed to be the longest-serving county employee in recent memory. The office celebrated with a party for Axford, including a plaque and a bouquet of flowers.The longtime legal secretary has typed details of the most high-profile cases in county history — including killers Clark Hazen and Warren Forrest.Axford has worked under five county prosecutors and, she said, 10 presidents.The staff of six is now close to 100 people — the largest law firm in Clark County. And after so many decades, Axford said she still leaves work happy.
