Chicago police say March ended as the 13th straight month to see a drop in gun violence.

In a news release, the police department says there were 29 homicides during the month — 10 fewer than were reported in March of last year. And the department says there was a similar drop in the number of shooting incidents and shooting victims.

The department says that so far in 2018 there have been 108 homicides compared to 140 during the same three-month period last year.

The department says the drop in both homicides and shooting incidents that began early last year coincides with the expanded use of technology that helps police better identify areas where crimes might be committed and respond quicker to shooting incidents.
