A woman was killed and two teens seriously injured in back-to-back shootings during broad daylight in Dorchester Saturday, police said.

The first shots rang out just before 2:30 p.m. at the intersection of Washington and Morse street, leaving a woman, shot in the chest, dead before she was even transported to the hospital. A male teen of 15 or 16 was also hit, the  Boston Herald reported.

“We believe the younger kid was the targeted victim here,” Police Commissioner William Evans told reporters during a press conference.

Police scoured the streets for evidence, but Evans urged residents to step up.

“When you have a female and young kid shot in broad daylight, people need to take responsibility. Please step up. We are looking at video, we are looking for witnesses,” Evans told the Herald.

Police responded to a second shooting at the intersection of Waldeck Street and Geneva Avenue two hours later, where one teen was non-fatally shot.

Community members were left reeling in the wake of the shootings.

“This is a community. This is where people live, this isn’t the Wild Wild West,” one woman who did not want to be identified told WCVB.

Another resident who declined to give his name agreed.

“We should be able to walk down the street and not have to worry about ducking from bullets and running for cover,” he said.

All three victims were transported to Boston Medical Center, where the woman was pronounced dead.
