Detectives investigating the murder of a farmer run over as he tried to stop his Land Rover being stolen said they were pleased with the public response to their appeals for help.
Warwickshire Police said the incident room had received more than 50 calls since Michael Boffey was knocked down at his farm at Withybrook, near Rugby, on Saturday morning.
Detective Chief Inspector Sarah Goodall, who is leading the investigation, said the calls had prompted several lines of inquiry, which a dedicated team of more than 20 officers were pursuing.
Ms Goodall said: "The response has been extremely encouraging. We are grateful to all the people who have taken the time to contact us."
Mr Boffey, known as Mick, died from head injuries at the scene of the collision at Grange Farm in Featherbed Lane.
The 61-year-old father of three, who lived in Burton Hastings, near Nuneaton, is thought had been trying to block off a gateway when he was hit.
His pet dog Jack, which had been left in the green 4x4 but was later found in another vehicle in the farmyard, is said to be pining for his master.
Mr Boffey, a grandfather of five, was inseparable from his border terrier, an ex-stray, which travelled everywhere with him.
Police are still appealing for help to trace a silver saloon car seen in the farmyard moments before the theft and in the lane shortly after.
Anyone with a silver car who was in the Wolvey or Withybrook areas between
10.30am and noon on Saturday is asked to contact officers so they can be eliminated from the investigation.
Mr Boffey's death prompted calls from victim support campaigners for a minimum 25-year sentence for the killers of people who die protecting their own property.
Norman Brennan, director of the Victims of Crime Trust, claimed ineffective sentences were failing to protect victims such as Mr Boffey.
