Sorry for your tough day Sad Eyes. Grief from murder is different and in many ways very,very difficult. You sound like you are working with it. Blessings to you and your family. Are you familiar with the work of Lula Redmond? She wrote a book some time ago for professionals on murder that was a landmark book. I think the introduction is available
online at amazon. You might want to have a look at it. The book is old but the info is excellent. It's for professionals but I think you might be able to extract some things that might be helpful.
