Cork Circuit Court heard from Megan Johnston’s mother, Valda on how Megan’s death has impacted her life.
Valda suffered a stroke in December 2012 and is now confined to a wheelchair.
"When I got sick, Meg gave up college and was 100pc there for me as a carer and emotionally she was the one person I kept going for - her daily visits to the hospital, taking me out on trips, running our home.
"She did all this with a smile, a giggle and love - I cannot express how brilliant she was with me - I knew we had a special bond and I didn’t want her to give up her lifestyle for me but she did and I loved her for making me feel safe, loved and never treating me any differently that she did before I had my stroke
"When she was walking on the ward every day with her red hair and stunning smile, I thought I knew life would be okay - I always laughed when she was with me. Meg was my life, my fugture, my daughter, my friend.
"When I heard that on April 8th 2013 that Meg had been killed in a car crash my world fell apart .... When Meg was taken, I lost my permanent carer, my confidante, my reason for getting up and fighting my illness.
Ms Johnston said that she was aware her daughter and Casey were friends but she believed that he must made accountable in some way
Stephen Johnston, Megan's father - also suffered from ill health since 2006 and Megan drove him to hospital appointments.
"It all happened the wrong way around - I was never supposed to bury my daughter."
Spoke about the cost of her burial putting strain on her mum and himself. "We are now saving for a headstone, a place to visit Meg and remember her, although I’m up every morning with her on my mind and remember all the happiness she brought to my life."
