He was an officer in Northern Ireland, and was promoted to Major when he was discharged with honor.

After pleading guilty to the causing death of careless driving, he appeared at St Albans Crown Court for his sentencing.
Ginder was sentenced to a 10 month imprisonment with a suspended term of two years.
The curfew was enforced for four months, between 8pm to 6am. He also had to stop driving for one year.
Prosecutor Will Noble said: ‘The prosecution say he performed some observations but failed to notice the Mazda in lane two.
He crossed lanes one and two in the same second.
He would have seen Mazda, and not run out of it if he had paused.
“The prosecution said it wasn’t dangerous driving. In just 3.2 seconds, he had travelled from slip road to lanes two.
The court heard that Ms Malone had been Ginder’s girlfriend for three years.

Ginder, who pleaded guilty for causing death through careless driving, appeared at St Albans Crown Court to face his sentencing.
Trevor Burke, QC, defended Ginder and said that he was of good character without any previous convictions.
According to Mr Burke, he hasn’t ridden a bike since that incident and doesn’t plan on riding one again.
“This tragic accident was as brief and poignant as it was. This incident was not caused by very poor or persistent driving.
He made the correct shoulder turn as he entered A1M.
The victim was her partner. He loved her, and she loved his. Together, they were determined to spend the rest of their lives together. He had taken his love for motorcycling to her.
“She passed her test, and she bought her bike. The two of them would take motorcycling trips together.
She was dedicated to her job at Addenbrooks. There were many people she loved and admired.
“She was clearly much loved, not least by the defendant.”
Judge Michael QC Kay declared that this was a tragic incident. There have been terrible consequences for defendants and Ria Malone’s family who sit in court. It is impossible for me to make things right.
“This was not what anyone wanted. It was unimaginable. It is an awful tragedy.
