A Pine Bluff man arrested Tuesday after marijuana plants were found growing in his residence had a unique reason for them being there.

Stephen O’Bryant, 34, told sheriff’s investigators the plants were a “science project and for his personal use,” Tri-County Drug Task Force Investigator Bo Hudson said in a probable cause affidavit presented in district court Wednesday.

According to the affidavit, task force investigators and members of the Criminal Investigations Division served a drug-related search warrant at a house in the 2600 block of South Linden Street and detained O’Bryant and a female who were in the house.

During the search, a .22-caliber revolver was found on a couch, along with a black digital scale. On a shelf by the living room door were two plastic bags containing stems, a can containing stems and an orange pill bottle with seeds in it. There was also $240 cash on the shelf.

Hudson reported that a white, toilet-shaped bowl was found on the couch; it contained a green vegetable substance, along with a handwritten sheet of instructions for growing marijuana. Three marijuana plants were found in the bedroom, and one marijuana plant was found in the bathroom.

A female who lived in the house said she had lived there for about a year and knew the plants were in the house but said they were not hers. She said she smokes marijuana and said the bowl belongs to her but said she did not grow marijuana.

When O’Bryant was questioned, he said he lived in the house and was there when the warrant was served. He also said the plants belonged to him and said the gun was an inheritance from his father. O’Bryant said the seeds that were found were old and that this was the first time he had ever grown marijuana. He said he would ground up the stems to make tea.

On Wednesday, Jefferson County District Judge Kim Bridgforth set a $5,000 bond for O’Bryant, who had no prior convictions or pending charges after ruling prosecutors have probable cause to charge him with manufacturing a controlled substance and with simultaneous possession of drugs and firearms.

An attorney appeared at the court hearing with O’Bryant.
