The recovered mail was apparently stolen from a cluster of mailboxes within the 56200 block of Reche Road in Landers, north of Joshua Tree, sheriff’s officials said. An investigation determined voter ballots were not being targeted, just incoming mail.

All the residents with mailboxes in the area were contacted by deputies, and no more victims were found, authorities said. The case has been forwarded to the United States Postal Inspector for further investigation.
