The father was at home with his 18-year-old son. They were planning to attend an afternoon memorial service for his wife, Tory Shaw who died of cancer a week earlier.
"I am so angry, because this was a good person who cared about people," cried family friend, Cindy Whittaker.
During the two minutes the masked men were inside the home, Shaw's brother-in-law tells us Rick put up a fight and was about to reach for his own gun to defend himself and his son when he was fatally shot in the chest.
Moments later, the four suspects are seen on the surveillance video running away from the house.
They are the same suspects police believe busted into a 1st Street North home 20 minutes earlier, taking jewelry and cash from 51-year-old Gregg Gordon and his wife.
"We're dealing with suspects that are strangers to the victims, or so it appears, and that's an obstacle for us in the investigation. That's why is so critical to get the community step up to the plate and give us information to help us close these cases," said Bill Proffitt, a St. Petersburg Police spokesman.
Rick Shaw was shot inside his house where his wife of 18 years died a week earlier after a long battle with cancer. The family, like detectives are working hard to find out who killed the father.
"They've proven their disregard for human life, they've proven they're violent and these are people we want to get off the street," said Proffitt.
Anyone with information is asked to call the St. Petersburg Police tip line at 727-892-5000.
