Patrolling a south Brownwood  neighborhood because of its proclivity for drug arrests, deputies made a traffic stop late Friday night and arrested three on first-degree felony charges, a deputy's report states.

Deputies found 7 grams of methamphetamine in a diaper bag on the vehicle's floorboard and also found a semi-automatic handgun, a report by deputy John Gramling states.

Deputies arrested Gary Hollis, 23, of Rising Star, Hilary Lee-Millican, 23, of Odessa and Summer Sanders, 20, of May, Brown County Jail records state.

All three were charged with manufacture or delivery of a controlled substance in a drug free zone, and Hollis was charged with unlawful carrying of a weapon.

According to Gramling's report:

Gramling and sheriff's narcotics detective Carlyle Gover were on a drug interdiction patrol in the area of Third and Coggin around 11 p.m. Gramling saw a 2004 Ford F-150 circle the intersection of Third and Avenue J twice, and the driver failed to signal when making a right turn from Third onto Coggin.

Gramling made a traffic stop at Third and Avenue H. Gramling noticed a "large amount of nervous behavior" and believed he was hearing an "improbable story" from the occupants. The driver denied consent to search, and the deputies called for sheriff's K-9 handler James Stroope and his drug dog.

The dog alerted on the pickup and the deputies conducted a probable cause search, Gramling's report states. The occupants denied knowledge of the narcotics and the gun.

In an unrelated drug arrest, Brownwood police were dispatched Friday to the 800 block of Avenue A on a code violation report.

Police found prescription medication but no prescription and arrested Jennifer Jolly, 43, of Brownwood, on a charge of possession of a controlled substance, jail records state.
