Residents gathered Wednesday evening at Pontiac Point in Lafayette to call for an end to gun violence plaguing the community, including two shooting injuries and two fatal shootings in December alone.

Police have investigated 16 shooting deaths within the city limits this year, up from nine in 2014 and 10 in 2013, according to information released by the Lafayette Police Department and compiled by The Acadiana Advocate.

Four of those killed were between 18 and 19 years old, seven were between the ages of 21 and 33 and five were between the ages of 44 and 64.

As of Wednesday night, accused shooters had not been identified in at least five of the killings, including the Dec. 10 slaying of 57-year-old Rosando Gonzales, of Lafayette, on Surrey Street.

Officers this year have also investigated at least 35 nonfatal shootings, with at least 24 people — of whom seven were teenagers — injured by the gunfire.
