THE VILLAGE OF INDIAN HILL, Ohio -- Ohio State Highway Patrol troopers arrested two Arizona women and seized more than 4 pounds of heroin last week.

Troopers stopped the women in a 2008 Nissan Altima at about 3:20 p.m. July 8 for an impeding traffic violation on Interstate 275 in Indian Hill. In a news release, OSHP said the troopers observed "criminal indicators" during the stop and brought a drug-sniffing dog, which indicated there were drugs inside.

A search of the car turned up the heroin, which troopers said was worth about $300,000.

Driver Gloria Lopez, of Tuscon, Arizona and 19-year-old passenger Lizbeth Sophia Morales of Sierra Vista, Arizona, were both charged with possession and trafficking in heroin and operating a vehicle with a false compartment.

If convicted, the women could each face up to 21 years in prison and a fine of up to $45,000.

Both women were being held in the Hamilton County Justice Center.
