What were the circumstances that led Jefferson to be arrested and put on trial for murder?

Jeffeson's friends wanted alcohol. Jefferson had no money, so they went to Gropé’s store, hoping he would give them some wine on credit. Gropé refused, and Bear, already drunk, attacked the storekeeper. A scuffle ensued, with Brother, Bear, and Gropé dead. Jefferson, unsure what to do, took a bottle of whiskey and some cash from the register and tried to run away, but two white men entering the store caught him and took him to the police.
