Sister of motorcyclist killed in tragic M50 crash makes heartfelt plea to drivers who sat with brother

The sister of a motorcyclist tragically killed in a horrific collision with a lorry on the M50 on Friday[1] has appealed to try and find the drivers who sat with her brother until the ambulance came. Derek Martin, 42, from north Dublin[2], who worked at Wheatfield Prison, was sadly pronounced dead at the scene after the motorbike he was riding collided with a lorry between the Liffey Valley and Castleknock junctions at around 10:15am. The truck driver, aged in his 50s, was rushed to hospital to be treated for injuries which are not believed to be serious.

A large portion of the motorway was shut into the evening[3] following the tragic collision, causing significant delays.

Derek's sister, Helen, has taken to social media to make a heartfelt appeal to motorists who stopped and sat with him "so he wasn't alone" as they waited for the ambulance to arrive at the scene. She wrote on X: "I've just been told that when my brother passed away on the M50 on Friday that several cars stopped and people sat around him until the ambulance came so he wasn't alone, I really want to find them if people can please share".

Thankfully, Helen's heartbreaking plea was answered, with one woman replying to tell her that she went to a car to cover Derek up after she realised he has tragically lost his life.

Expressing sympathy to the Martins for the tragic loss of Derek, she said: "Helen, I am so sorry for your loss. "I was one of those people, got out of my car and when I realised he had passed away, I went to my car and got a blanket to cover him and wrapped it around him. It was the least I could do.

My heart goes out to all of you."
