Stockton Police raided two homes Tuesday and found hundreds of pieces of stolen mail. After mail thefts increased, police stepped up their investigative efforts.
The investigation by Stockton police led to a home in north Stockton where a SWAT team served a search warrant and arrested two sisters.
Stockton Police Officer Joe Silva says hundreds of pieces of stolen mail were found in boxes inside the home, and outside, some of the mail had been shredded and put into a trash container.
Even though mail theft is investigated by federal law enforcement, Silva says dozens of complaints in the last month prompted police to take a greater role.
"That's why we're taking the initial reports and working side by side with the U.S. Postal inspectors on these investigations," says Silva.
Silva says investigators also found a firearm, narcotics and stolen prescription medication.
"These thieves would go around, rip off the community mailbox, and steal these prescription medications and then they sell them on Craigslist and other type of social media," he says.
Silva says officers also found a second home with stolen mail during a probation search.
