Mosby said she was particularly concerned with the level of retaliatory violence, and said she and Davis plan to go to Annapolis in the upcoming legislative session and push for tough punishments for gun possession.
Davis said 60 percent of the sentences for people convicted of carrying a gun this year were suspended.
Davis said he was also concerned with the high number of non-fatal shootings, saying such incidents often represent "unfinished business" for shooters or their victims.
"We have to make quick arrests, particularly in those non fatal shootings," he said.
Police, meanwhile, were investigating three shootings that occurred late Tuesday night and early Wednesday that injured a 17-year-old and two 26-year-olds.
Police said all three victims were "uncooperative" with detectives, refusing to give them locations of the shootings.
Police were called just before 5 a.m. Wednesday to the 17-year-old victim's grandmother's home in the 200 block of Furrow Street in Southwest Baltimore. The teen had with a gunshot wound in his arm, police said. Police said he left the home after arguing with his grandmother and returned after being shot. He told police he was shot at a bus stop, but did not elaborate.
The other two victims arrived at hospitals after being shot, one of them in the back of the neck around midnight and the other in the buttocks about 10 p.m. Tuesday, police said.
