A Victim"s Story

Imagine waking up in a hospital trauma unit and being told by a doctor that your 15 year-old-brother is dead. I wished I had died with him.

My mother and Dad lost a son, and my sister and I lost a brother.

He was anxious to try out his new rod. On the way up we stopped to get something to eat. Tim was a real outdoor person - he loved nature and outdoor activities. The crash occurred when a drunk driver crossed over the center line of the road and hit us head-on. Tim and I were rushed to a hospital.

VII impact of the crash VIII devastating on the whole IX .

I spent a couple of months in the trauma unit. I did not get a chance to say goodbye to my little brother. Tim"s funeral was held while I was in hospital. They say time heals all wounds - if that"s true then there are a lot of wounds still trying to heal...
