(Michigan City, IN) - A Chicago woman spent Christmas behind bars after she was allegedly caught with cocaine pressed into the size of a golf ball in Michigan City.

Michigan City Police say 28-year-old Michelle Jackson was a passenger in a vehicle authorities caught speeding on Michigan Boulevard about 3 a.m. Monday. During the traffic stop, police said a plastic bag containing nine grams of cocaine about the size of a golf ball was found stuffed between the front passenger seat and the seat belt buckle where she had been sitting. About five grams of marijuana was also allegedly recovered from inside a pocket in her jacket, police said.

Court documents show Jackson denied having any knowledge about the cocaine being in the vehicle. The search was conducted after police detected an odor of marijuana coming from the vehicle.

Jackson was still being held in the La Porte County jail Thursday morning on $15,000 bond and could face as much as a six year sentence.
