Madison police arrested what they said was a major distributor of marijuana this weekend and seized about 7.5 pounds of marijuana.

Detective Lt. Jonathon Simpson had received information for the past five months that Melba Yvonne Ortega, 48, of Vevay, had been supplying marijuana to Jefferson County, according to police.

The 7.5 pounds of marijuana police found at Ortega's residence had a street value of about $7,500. Police said they also found three cell phones, $300 in cash, a small bag of cocaine and a 9 mm handgun.

Simpson received information that Ortega would be in Madison on Sunday and went to the location where she was said to be. Simpson followed Ortega to a mobile home she recently rented and watched her carry items into the house, according to the police report.

After Ortega left the house, Simpson said she committed a traffic violation, for which he pulled her over. K-9 Laykos was brought to the scene to perform an exterior search of the vehicle and indicated the presence of drugs.

Officers searched the vehicle but did not find any drugs, police said. Police found the cell phones and money during the search.

Simpson planned to obtain a search warrant for the residence, but Ortega said she didn't want to wait that long and gave officers permission to search the home, according to the affidavit.

Police found two trash bags filled with marijuana in the house along with the cocaine and handgun, police said.

Ortega told police she bought the marijuana, which was from Texas, for $500 a pound and sold it for $1,000 a pound, according to the police report.

Ortega was arrested on charges of dealing marijuana, possession of cocaine and possession of a firearm by a serious violent felon.
