A woman and her two sons are accused of transporting meth from Texas to an Atlanta-area house.

News outlets report warrants for 56-year-old San Juana Barrera, 37-year-old Alex Perez and 32-year-old Cresencio Perez say they drove with more than 400 grams of meth stashed in their SUV's tires on Jan. 25.

Gwinnett County police's T.C. Joseph says Cresencio Perez said he brought his mother to allay suspicion. Barrera said at a hearing she didn't know her sons were transporting drugs. All three are charged with drug trafficking.

Investigators found what the DEA estimates as $1 million in crystal meth and liquid meth at the Norcross home.

Defense attorney Michael Marr says agents couldn't know how much meth was inside before the family arrived.

No other arrests have been made.
