The five separate shootings around the 110 Freeway were linked based on the type of ammunition being used, said Lt. Carmichael Octave of the L.A. County Sheriff's Department.
On April 18, a woman was shot in the arm while walking on Main Street at about 2 p.m. Four days later, another woman's car was struck by gunfire near the intersection of Normandie Avenue and Torrance Boulevard.
There was another shooting the next day on the 110 Freeway at the Carson Street exit. Then on April 26, there were two shootings. In one, a man's car was hit while he was driving down Figueroa Street near Lomita Boulevard. In the second, a man was shot in the ear while driving down the 110 Freeway near Torrance Boulevard.
People in the area say they're thinking twice now about walking down the street and where they're driving.
"It doesn't feel very safe that I could be standing out here and somebody could shoot me possibly," said Heidi Blas, who works in Carson.
But investigators say they are a step closer to finding the person responsible. They just need the public's help locating him before he strikes again.
"We obviously want to take care of the people of Carson, and care for the citizens of the community,"Octave said. "We're saturating the area with additional patrol units and we hope to bring this to a conclusion pretty soon."
The suspect was described as a heavy set Hispanic man in his late 20s to early 30s. He has a shaved head and a tattoo on the back of his head.
Anyone with information is urged to call the Los Angeles Regional Crime Stoppers at (800) 222-TIPS.
