Baltimore police detectives are trying to figure out whether a chaotic shooting attack on a crowd enjoying a weekend cookout might be frenzied competition between underworld groups, a case of a triggerman seeking vengeance, or some other kind of senseless strike.

But one thing’s for certain: In a city accustomed to gun violence the Sunday shooting that killed one and wounded seven others in a gritty West Baltimore neighborhood barely stands out in a sea of similar shootings in Maryland’s biggest city.

Cassandra Crifasi of the Center for Gun Policy and Research at Baltimore’s Johns Hopkins University said Monday that the weekend shooting exemplifies the kind of standard violence now seen in Baltimore.

No arrests have been made a day after the bloodshed at the crowded cookouts.
