Oh dear . . .I can really relate to this as I had something similar happen to me while in the midst of a move a little over a year ago and had all my sewing supplies in storage. The unit was broken into and my Koala quilting cabinet and Artista 180 were stolen along with many of my notions, etc. Oddly enough, my Elna 925 Serger was left, however, it was behind some larger pieces of furniture that was also left behind. I'm sure she's just heartsick.
If she's a member of a guild, or a church, maybe there's something you can collectively do. Bless her heart . . .she'll be in my prayers.
