Lincoln Police need your help in tracking down some vandals who damaged mailboxes in two different areas of the northwest portion of the city over the weekend. A woman living in the area heard a loud boom outside her home just after 2 a.m. Sunday and saw a mailbox knocked down. At least 18 mailboxes were damaged early Sunday morning near Campbell Elementary School. Officer Katie Flood said during police briefing that surveillance video from a home in the 4100 block of Mason Drive showed a dark-colored sedan pull up and a white male get out and kick the mailbox down. There are no suspects. Flood also said that there were four unrelated similar vandalism cases in the area around 15th and Fletcher early Saturday morning.
