Parkland, where the school is located, gets police service from the Broward Sheriff’s Office, and fire and paramedic service from the neighboring city of Coral Springs, which also has a police department. Cellular 911 calls from Parkland go to Coral Springs. Those callers needing police are transferred to Broward County’s 911 center. Almost all calls from Stoneman Douglas were from cellphones, which had to be transferred. That added about 30 seconds before each reached a dispatcher — if the call wasn’t disconnected.
