Police say a 15-year-old girl in Delhi (Merced County) sold marijuana out of her bedroom with the help of her mother.

The Merced County Sheriff's Office said in a Facebook post that deputies arrested 44-year-old Jose Reyes Martinez and 44-year-old Norma Angelica Alvarez after discovering a loaded AK-47 and 80 pounds of marijuana in the house on Aug. 17.

According to police, the couple's 15-year-old daughter sold the marijuana out of her bedroom, and received her supply from her mother.

Deputies seized "packaged marijuana for sale, marijuana edibles and other items associated with the sales and use of marijuana" from the daughter.

In addition, deputies found 12 large marijuana plants in a "makeshift green house" located in the family's backyard.

Child Protective Services interviewed the 15-year-old and another minor living in the house, and took both of them into custody.

In the Facebook post, the sheriff's office included a picture of the sign that was allegedly found on the 15-year-old's door.

The sign reads, "It's the law, you must be 15 years of age or older to purchase fireworks," although someone scratched out "fireworks" and wrote in "weed."
