Smith had assaulted his baby daughter on 26 August 2000 at the family’s home in Harrow when she was just four weeks old.
Smith had admitted to throwing the newborn across the room into her cot after becoming frustrated at her crying while his partner was out of the house.
This was inconsistent with her injuries and was picked up by the clinicians treating her straight away.
A full review of the medical evidence and a report was produced; the case was reviewed and Smith was further arrested on 12 February 2019.
Detective Sergeant Sarah Fisher, from the Met’s Specialist Crime Command, said: “This was a horrendous act committed by Dean Smith on his four-week-old baby daughter. She lived for fourteen years severely disabled and in constant pain due to the traumatic head injury inflicted more than twenty years ago.
“This has been a traumatic time for the family who have lost Maisie did not expect a murder investigation to take place, much less a retrial. My thoughts are with them today and I hope they can now move forward and feel justice has been done for Maisie.”
Statement from Tracey and Ian Newell: Maisie sustained unspeakable injuries as a tiny, vulnerable, innocent baby. We adopted her when she was 20 months. It was clear from the start that the consequences of her injuries were going to be profound, life long and life-limiting. We made a decision to commit to this beautiful little girl, to give her the best life we could, to maximise her potential and to love her unconditionally.
Maisie had complex and profound needs that arose as a direct consequence of her sustained brain injury when she was 4 weeks old; epilepsy, cerebral palsy, unsafe swallow, visual impairment and profound learning difficulties. There was not a functioning piece of her that was unaffected- she lived with pain, very limited purposeful movement and no verbal communication. But despite all the challenges she endured and despite her poor start to life, Maisie remained a strong, vibrant personality who drew people to her with her most incredible smile.
Maisie fought a brave battle and conquered many illnesses and health complications but at the end of her life she was enduring 6hrs of nebulisers, chest physio and cough assist machines alone a day. She was having increasing hip pain, vomiting blood frequently and often her bowels or bladder were struggling to function. After contracting flu she ended up on a life support machine and when she was extubated she had lost her cough/gag reflex. She was unable to clear her secretions anymore and succumbed to a chest infection.
She was brought home to die and her last week was peaceful and pain-free, surrounded by the love of her family.
It has taken over seven-and-a-half years since her death for her case to be heard in court. She should have had a safe, happy, carefree childhood. She should have now been becoming independent, finding out who she wanted to be, the world should now be her oyster. But instead, she was robbed of all those opportunities.
We gave her our best and she couldn’t have been more loved. We all continue to love and miss her. She was adored by us all and we will continue to do our best by ensuring justice prevails. She had no voice of her own, we will be her voice.
