This story is from the late 80s or early 90s. It doesn't show up in the LV RJ's archives.
Friend of mine in Vegas, a dentist, ran a practice with his wife, also a dentist.
One night she didn't come home. She was in the habit of working late and then visiting family, so he put the kids to bed and thought no more about it until the next morning. He woke up, and she was not home.
He didn't have long to wonder about it; one of the staff called him from the office: his wife was sitting outside the office in her minivan with a gunshot wound to the head. He was understandably distraught.
Among the other things he did shortly after that -- new security system, mag locks on the front door, CCTV -- was equip himself with a pistol and purchase a similar pistol for the office. He paid for their training, instituted security policies, and made sure that at least one staffer was within easy reach of that pistol at all times. Any new staff were also trained.
Yes, he had one girl decide she couldn't bring herself to work in that neighborhood any more (and this was in a high-traffic section of Sahara Ave), but the rest were entirely fine with arming up.
This was before I had any personal interest in firearms, but discussions with him afterward were one of the things that led to my eventual understanding that our personal safety & security is up to us.
On the one hand, he took serious precautions to secure his office and his staff. On the other hand, more than once I got the sense that he wouldn't have minded if the murderer had come back to try it again. No actual words, just a look and a set to his jaw.
My take-away from that, which wouldn't mature for a few years, became "don't leave your family or your staff defenseless."
