Mother's Pain Over Robbery Death
Craig Hodson-Walker, 29, was blasted in the chest as three masked men raided his parents' village post office and shop on Friday morning.
The three men who raided the shop - all believed to be in their 20s or 30s - were armed with a handgun and a sledgehammer.
They shot Craig's father, Ken, in the leg during the attack on the Fairfield Post Office and Stores in north Worcestershire.
Craig's mother, Judy Hodson-Walker, said she was "devastated at the death of our beautiful boy who died protecting the people that he loved".
"Why did such a beautiful, honest, hard working human being have his life taken away in that way?" she said.
"He didn't do anybody any harm and will be so greatly missed by each and everyone who knew him.
"I just don't understand why it happened like it did �?? it all just seems so senseless."
Police think the three "dangerous" men were joined by a getaway driver.
More than 100 officers have been signed up to track them down, and the Post Office has offered a £50,000 reward for information.
One of the gang was white and about 6ft tall and wearing a dark hooded top and tracksuit bottoms. The other two were shorter but also wearing dark clothing.
The fourth offender is thought to have been a getaway driver who waited outside in a silver VW Golf.
The robbery happened at about 8.20am on Friday and the offenders sped from the scene - the Golf was later found abandoned on a nearby road.
Detectives said it was likely that the car, which had false number plates, had been caught in rush-hour traffic near the post office and they are urging anyone who saw the vehicle to contact them.
They are also interested in hearing from anyone who saw a white car driving at speed in Bournheath Road between 8.15am and 8.30am yesterday.
Sky News correspondent David Crabtree, at the scene, said police have a tough job on their hands to catch the "ruthless" killers.
"They could be anywhere in the country by now," he said.
But Detective Superintendent Jon Groves has made his goal clear, saying: "I can assure you that we are determined to bring these offenders to justice as soon as possible."
Ken Hodson-Walker is said to be in a stable condition in hospital following surgery.
Friends of Craig, who was engaged to be married, have been remembering him as someone who "loved his parents to bits".
Close pal Alice Raybould, 29, said: "He is - I should say he was - the nicest and kindest person I've known in my life."
A group has been started on social-networking site Facebook, called Rest In Peace Craig Hodson-Walker.
A post-mortem examination is scheduled to take place tomorrow.
