Help us put my Sister and Brother-in-law to rest

Last night we got the news that my Sister and her husband got their life taken away unexpectedly they were shot and kill in front of there apartments , they leave behind 3 daughters, we are so in shock we can believe it feels unreal ,how life can be taken away in the blink of an eye.. We are not ready for situations like this, if anyone would like to help and donate every penny counts.. My parents and siblings will be thankful for any donation.. Thank you
