Families of those killed by the Plymouth shooter say the world is a darker place without them.
They told of their grief amid questions about how killer Jake Davison was allowed a shotgun licence.
Relatives paid tribute to Lee Martyn, 43, who died trying to shield three-year-old daughter Sophie.
She was pushing a toy pram alongside her dad when Davison opened fire with a pump-action shotgun, having already killed his mum Maxine, 51.
Witnesses said Mr Martin was shot in the back but fell on his adopted daughter as he spent his final moments trying to protect her.
His widow Becky, 42, is an intensive care nurse who has been treating Covid-19 patients.

Lee’s cousin Jess Morcom said: “He had the kindest heart, would do anything for anybody and you only had to take one look at him to see how much he loved and adored his family, Bex and his children.”
She added: “Beautiful little Soph, my darling, how truly blessed we all were to have seen you grow into such a beautiful, funny and clever girl for the three years that we had with you.
“My heart hurts so much thinking about how it should have been so many more. I will miss your cheekiness and your dancing.
“I will think of you both every single day for the rest of my life. The world is going to be a much darker place without you in it.”
After killing Sophie and her dad, Davison, 22, went to a nearby park where he shot Stephen Washington, 59, who was walking his dogs.
His grieving relatives said: “Stephen was a friendly, outgoing person. He would help anyone at the drop of a hat, he loved his animals and was often seen walking his two huskies in the area.
“Our world has been turned upside down in the blink of an eye and he will be sorely missed by everyone who knew him.”
Widow Sheila described Stephen as her soulmate, adding: “Fly high, you’ve earnt your angel wings.”
Mourners signed a book of condolence at a memorial service on Sunday near the scene of the shooting in Keyham, Plymouth.
Outside St Thomas’ Church, Father David Way told why he had prayed for gunman Davison as well as his five victims.
He said: “I really thought long and hard about that... but he was a Christian, so I felt I had to. Our gospel teaches of forgiveness, and I thought it was important.
“We should also remember that he is a product of the world we live in, where the majority of people are on social media, and are subjected to extremist views and hatred.
“We are becoming increasingly aware of the influence of that.”
Survivor Ben Parsonage, 33, has left hospital following the attack but his mum Michelle, 53, will need an operation to fix her arm before she is also discharged.
Davison also shot Kate Shepherd, 66, before turning the gun on himself. Bystander Bert Pinkerton kept Ms Shepherd conscious until paramedics arrived, but she died in hospital.
Davison, said to have a history of obsessive compulsive disorder, anger issues and depression, was nevertheless handed back his shotgun licence last month.
It had been confiscated following allegations of assault, but returned after he agreed to an anger management course.

Police said they did not trawl his online activity before allowing him to carry a deadly weapon because it would have been an “invasion of privacy”.
If they had, they would have discovered a string of hate-filled rants in which he spoke of himself as a Terminator and posted on “incel” forums – an online subculture of involuntary celibates angry at women for not finding them attractive.
Former Met Police commissioner Lord Stevens said: “The videos he made should have been taken into account when he applied for a shotgun licence.”
All forces in England and Wales are being asked to review their firearm application processes and whether they need to revisit any existing licences.
In the wake of the tragedy, new guidance planned by the Home Office will mean social media checks are carried out on anyone applying for permission to own a firearm or shotgun.
The Home Office said: “We are bringing forward new guidance to improve how people applying for a firearms licence are assessed in future.”
