The gun collection will be held on Saturday, Dec. 15 from 10 a.m. to 2 p.m. at St. Mark's United Methodist Church, 601 Eighth St.
The program, the third of three held by county police, allows gun owners to anonymously turn in a weapon — new or used, functional or not — and in return, get a gift card of up to $100.
Firearms should be unloaded and left in the trunk of participants' vehicles. A uniformed police officer will greet participants and provide directions. Unwanted ammunition can also be turned in.
During the first two events, police officials said about 300 guns were recovered.
