The circumstances leading up to the death of a young mother found in an overturned car off a dual carriageway are still a mystery, an inquest has heard.

Sinead Symes, 28, died on the A414 near Potters Crouch - just beyond the Park Street roundabout - when driving back to her home in Hemel Hempstead from her parents’ house in Borehamwood on October 4, 2015.

Her car veered left and overturned in a stretch of woodland off the road.

Her husband, Nathan Symes, reported her missing at about 6.30pm and went looking for her with his father. He discovered his wife at 1.17am in her overturned black Renault Clio.

The reason why the car veered off the road remains a mystery and no witnesses came forward.

It is believed that after the car came off the road, the driver’s side hit a tree which may have contributed to her death.

An the inquest last Tuesday, October 18, Herts coroner Geoffrey Sullivan ruled the cause of death as a road traffic crash.

Sinead was born in University College London Hospital in 1987 and grew up in Borehamwood, attending Monksmead First School, Furzehill Middle School and Hertswood Upper School. She worked at MPL Home Ltd, in Hemel Hempstead.

She leaves behind her husband Nathan, her parents Chris and Kathleen Hare, brother Peter, and daughter Orla Rose Symes.

At the time of her death, Nathan said: “Sinead was a gorgeous, caring, and trustworthy person, whilst also being a truly independent woman who just enjoyed having fun, and whose smile and laughter was infectious with anyone she came across.

“She was the most fantastic and dedicated mum to our beautiful daughter Orla Rose, for whom I am eternally grateful for and I vow that Orla Rose will grow up knowing her mummy.

“I am so proud and honoured that although Sinead and I were together for almost seven years, I was able to call her my wife for 106 days.”

He continued: “Sinead will always be a part of me and she has made me a better person for just knowing her. There is now a massive hole in our family due to Sinead leaving us that will never be filled.

“However, neither I, nor Orla Rose, will ever forget her. We will continue to love her forever and always.”
