Officers are on the lookout for one of the three men who robbed a drug dealer at gunpoint last week, Hammond Police reported Tuesday morning.

On Dec. 17, Kevon Trotter, 22, of Hammond, called police and said his cell phone, money and laptop had been taken during a robbery in Clark Park.

He didn’t tell officers that just before the robbery he had sold marijuana to 19-year-old Brittany Landry, of Ponchatoula, police reported. Police added that Landry called Trotter to meet her in the park to sell her drugs, and she arranged the robbery with three “associates.”

The trio of 19-year-olds — Trevon Robertson, of Amite; Bradley Patrick, of Hammond; and Brandon Patrick, of Hammond — approached Trotter’s car with handguns drawn as Trotter and Landry smoked marijuana in his vehicle. They made off with a “small amount” of cash, his cell phone and a half-ounce of marijuana, Hammond Police reported.

After Trotter reported the robbery, officers waited for Landry at her home. When she returned, Landry saw police vehicles and did not turn into her driveway. Officers pursued her. Before she stopped her vehicle, two men jumped out and fled, escaping capture, Hammond Police reported.

Officers arrested Landry on a count of principal to armed robbery and Robertson on a count of armed robbery. Bradley Patrick was later arrested and also faces a count of armed robbery.

Trotter faces one count each of filing a false police report and conspiracy to distribute marijuana.

Police were still looking for Brandon Patrick as of Tuesday morning.
