God bless you for your efforts, care and concern. You were there for a reason, and I'm sure those involved appreaciated your actions, The mere fact that you have shown such concern and stopped leads me to believe you were their "Good Samaritan". I pray that you find confort soon, Its incidents like this that remind us how precious life is. No matter how many times you witness life slip away no matter the cause, there is always some sadness.
