A 33-year-old Sacramento man was shot at about 1:35 p.m. Sunday outside of a relative's home in the 100 block of South 20th Street, Detective Nicole Abetkov said.
The man was talking with several family members in front of the home when someone walked up and opened fire, hitting the victim three times, Abetkov said.
He was airlifted to John Muir Medical Center and was listed in serious condition as of Sunday, she said.
Witnesses said the shooter fled on foot.
On Saturday, there was a shooting in front of Uncle Sam's Liquors in the 3300 block of Cutting Boulevard at about 6:10 p.m., Abetkov said.
Three people were injured, and one was airlifted to John Muir with critical injuries. The other two victims suffered wounds to their legs and took themselves to Kaiser Permanente Richmond Medical Center, where they were treated and released, Abetkov said.
Witnesses told investigators there were one or two suspects in that case, Abetkov said. No arrests have been made.
Police are offering a $2,500 reward for information that leads to the arrest of suspects in either shooting. Anyone with information on either case is urged to call Richmond police at (510) 232-TIPS. Callers may remain anonymous.
