I am so sorry to hear of the loss of your daughter. We can take comfort in knowing that not for a moment has she been separated either from God's love and protection or from your love. Jesus' resurrection supremely and tangibly proved that murderous violence against him was not the victor. This is reflected in Paul's words (1Co 15:26,55,57-58):

26 The last enemy to be destroyed is death... 55 "O death, where is your victory? O death, where is your sting?"... 57 Thanks be to God, who gives us the victory through our Lord Jesus Christ. 58 Therefore, ... be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain.

You also may find helpful another BibleTexts.com webpage on "Paul - from terrorizing Christians to Christian brother, Christian evangelist, and Christian healer" at http://www.bibletexts.com/terms/paul-from-terror-to-ministry.htm#vision, which is an excerpt from a talk I delivered when I was serving as a prison chaplain in an area with a long and brutal history of violence. In my very frank dealings with and prayers of forgiveness for inmates, I had a continual expectation of the Holy Spirit's transformation of these individuals to be new Pauls -- from a life of violence to Christian brothers & sisters, Christian evangelists, and Christian healers.
