A mum is still hoping for justice 20 years after the hit-and-run death of her 12-year-old daughter.

On May 19, 2003, Gemma Rolfe was on her way to Girl Guides with her stepdad Dean when their car was hit by a stolen van on Slade Green Road, Erith.

The Erith School pupil had to be cut from the wreckage and died at the scene.

The van driver fled the accident and to this day no one has been charged in connection with Gemma’s death.

The accident took place near the junction with Canada Road, Slade Green, at about 7.10pm.

Two decades on, mum Janet Robey is more determined than ever to have justice for her child.

She said: “I just want someone to be responsible for killing my daughter.

“I know they didn’t go out that day planning to kill somebody but they did, their actions meant that I lost my daughter.

“My son lost his sister, my dad lost his grandchild – it impacted so many people and that person needs to be responsible.”

Recalling the day, Janet said: “I’d been to work and I was running a bit late so my husband picked Gemma up from school and took her home and everything was all a bit of a rush.

“I remember she had ham and pineapple pizza for her dinner and got changed and ran out the door to go to Girl Guides and said ‘see you later mum’.

“It was quite strange because whenever Gemma left the house I’d always stand at the door and wave goodbye and say ‘love you’ but that day I didn’t because everything was just such a rush.”

She said the next thing she knew, she’d gotten a phone call to say there had been an accident.

She continued: “I remember knocking on a neighbour’s door and they drove me to the accident scene but it felt like he was driving two miles an hour and I got there and I don’t think the car even stopped and I was running down the road.

“It’s all a bit of a blur and I don’t remember too much about it but they made me go into somebody’s house and a police officer came in and he told me that Gemma had died, my whole world crashed.”

Dean had been taken out of the car and taken to Darent Valley Hospital, Dartford, after breaking his left ribs and collar bone.

Janet’s twin brother Richard arrived at the scene and he took her to the hospital, which is where the family got to say goodbye to Gemma.

She said: “The hospital were amazing, so many family members came to the hospital that night.

“We all got to go in a room and say goodbye to Gemma before they took her away.

“Dean was there as well, he didn’t know when he got there that Gemma had passed away, it was me that told him.”

Gemma died instantly after suffering a head injury.

“If anything it’s a saving grace that she didn’t suffer,” Janet said.

“Dean had been taken out of the car and he was in the back of the ambulance and I stayed because at the time I didn’t know that Gemma had died.”

Janet says police at the time had suspicions about a van with several people in it, but proving who was driving would have been impossible.

She added: “I remember them telling me there wasn’t anything more they could do.

“When we had the inquest, it was an open verdict so if anybody does ever get caught for it or comes forward it’s not down as accidental, it’s down as open verdict.”

Every year on the anniversary, Janet lets a balloon go and puts flowers down at the site.

She said: “I never ask anybody to come, if anyone remembers they can come, and people do still come after all this time,

”Gemma’s name goes on the fence with pictures of her, how many years it’s been, just to keep people aware.

“People don’t come and know me as Janet, they know me as ‘Gemma’s mum’.”

The family are inviting people to come down to the junction of Slade Green Road and Canada Road today to remember Gemma, 20 years on.

A minute of silence will be held with people are being asked to arrive between 6.50pm and 7pm.

Janet added: “I want support for my daughter and our family, 20 years is too long and it’s not fair.

“I normally just go and do my thing but this year I wanted to do something because it’s been 20 years. It’s just too long for my daughter to walk out the door and say ‘see you later mum’ and I’ve got nothing, literally nothing.

“I was talking to one of my friends and I said to her it’s 20 years, I don’t even need to close my eyes and it feels like yesterday.”

Gemma was five foot nine and a half, “very very clever” and “such a kind and caring person”.

“She would do anything for anybody,” Janet said.

“She would make things and if it was Mother’s Day she would go round the neighbours and see if there were any jobs she could do to get some money to buy presents for me.

“Dean’s got a deaf brother called Gary who idolised her and Gemma was trying to learn sign language to communicate with him.

“There was a Scope collection bag and I didn’t know that Gemma had taken the bag up to her bedroom and filled it with stuff she didn’t want anymore.

“She put a letter in there and it was a poem about Gary and I didn’t know anything about it until they sent Gemma a letter to say they were going to put it in their magazine.

“She was just so very thoughtful.”

A police spokesman said: “Our thoughts remain with Gemma’s family and friends on the approach to this sad anniversary.

“The investigation remains open and though many years have passed, we remain committed to achieving justice.

“The case was last subject to a review by the Serious Crime Review Group last year and a number of inquiries remain ongoing. These are led by the Serious Collision Investigation Unit.”
