THE cause of an accident in which a motorcyclist died may never be known, according to a coroner.
Spilsby and Louth Deputy Coroner, Dick Marshall, recorded the death of Frank Herbert Cartledge as an accident.
The 64-year-old from Skegness died following a collision on the A1084 at Bigby Hill near Brigg on July 28.
Mr Cartledge was found in a grass verge by cyclist Michael Cella who stopped at the scene after seeing a wheel in the long grass.
He saw a motorcycle upside down then found Mr Cartledge unresponsive in a ditch.
Mr Cella found a small brown terrier dog in shock in a bag between the motorcycle and Mr Cartledge.
A post mortem report showed that Mr Cartledge died from multiple injuries.
No alcohol or drugs were detected in his body.
PC Michelle Ford, collision investigator for Lincolnshire Police said there was impact damage to the front of the Honda 650cc motorbike and brake marks on the carriageway.
She said: “There was nothing obvious at the scene as to why Mr Cartledge braked. I am confident the motorcycle was not going at an excessive speed.
“Looking at the bike it had not had contact with another vehicle. There were no marks on the carriageway other than the braking marks.”
Mr Cartledge was seen on CCTV in the Brigg area at 3.05pm with a probable time that the accident happened at around 3.10pm-3.15pm
A police appeal for witnesses was unsuccessful.
The inquest heard that Mr Cartledge regularly had his dog in front of him when he rode his motorcycle.
The dog was in a tank bag which was secured with a chain.
Mr Marshall said: “I cannot be certain of the cause of this particular accident.
“We do not know if the accident was something to do with the dog or something completely unrelated.
“There was no evidence at the scene or evidence of another vehicle being involved.
“I do not think we will ever know the cause of this accident.”
