Lompoc police say they found more than 28 grams of base cocaine at the home of Clara Garrett.
The drugs have a street value of about $2,800.
Detectives executed a search warrant at Garrett's home about 8 p.m. Tuesday.

Garrett was arrested and faces possession for sale of base cocaine, possession of smoking paraphernalia and a higher than usual bail amount because of a prior case that involved possession of a controlled substance.
