Alexandra shared some memories of Virginia and Elise, saying both were absolutely wonderful people.
"Elise was the most amazing sister the world could ever ask for. She was absolutely in love with animals and babies and playing dress up. She and my mother were on their way to meet my mother's grandfather and introduce them before he passed away. This death was sudden and not right and we are absolutely devastated by our losses," she wrote to FOX 13.
