What a tragedy!
For those that see a dog that 'might' be lost or need help. Do not chase it. That will cause most dogs to keep running. Instead, get the dogs attention, and either squat and act like you've found the most interesting thing ever, and many dogs will come see what you've found, or once you've gotten it's attention, go in the opposite direction, many dogs will follow you.
I've had my beagle picked up from my yard so many times that I no longer let her off leash. I live in the country where there is no leash law, but people will see her, assume she is lost for some reason, and pick her up. Luckily she is microchipped so quickly comes back home. Once she was gone a week, and when returned, the guy kept saying what an excellent hunter she was... newsflash, she's gun shy and not a hunting beagle. She lives inside.
RIP to Jacqueline and Ringo. Prayers for their families.
