Four people were arrested at an east side Windsor home Tuesday where Sonoma County sheriff’s detectives found 13 guns, cash and drugs, a sheriff’s official said Wednesday.

The arrests followed a two‑week investigation into drug sales and gun possession. Tuesday morning detectives went to the Strech Lane home with a search warrant, aided by the sheriff’s SWAT team, sheriff’s Sgt. Spencer Crum said.

About 10:15 a.m. the SWAT team surrounded the home and officials called for residents to come out, using a public address system. No one came out until after a second, loud “flash bang” device was detonated on the property. Three people exited the front door and a fourth person was stopped when he drove up to the home.

A search turned up guns throughout the home and garage: three handguns, six shotguns and four rifles, most loaded. One was an illegal short-barreled assault rifle, Crum said.

Deputies also found high-capacity ammunition magazines, a bulletproof vest, almost 100 grams of methamphetamine and heroin packaged for sale, counterfeit money and more than $8,000 in cash. A search of a Toyota Camry turned up a small amount of drugs, about $500 in cash and notes indicating drug sales, Crum said.

Terence Martin, 31, was arrested on suspicion of several felony charges including possessing the illegal rifle, possessing an assault weapon and a stolen gun, and animal cruelty. Bail was set at $60,000.

Fabian Markam, 36, who had been driving the Toyota, was arrested on suspicion of possessing drugs for sale and transportation. Bail was set at $40,000. Two women at the home were arrested on suspicion of misdemeanor possession of drug paraphernalia.

Martin, Markham and one of the women lived at the Windsor home. A dog belonging to Martin was found to be in need of medical care and was taken by a county animal control officer, Crum said.
