Brown, 25, faced 10 charges including first-degree murder, disinterment and mutilation of a dead body and arson in Circuit Court.
At the conclusion of the trial that started Feb. 6, the jury deliberated about two hours Thursday and less than two hours Friday, asking for some exhibits along the way.
Brown of Sterling Heights is charged in the deaths of Vernithea McCrary, Natasha Curtis, Demesha Hunt and Renisha Landers, whom he met through the classified advertising website Backpage.com, which is geared toward adults.
Brown is accused of killing the women in two separate incidents at his mother's Sterling Heights home, loading their bodies into cars and leaving them in a blighted area in his old neighborhood in Detroit. Prosecutors said he caught rides home after dumping the women, who were found in pairs. The bodies of one pair of women were set on fire.
Wayne County medical examiners testified that they believed the women were asphyxiated or suffered an asphyxiation-type of death. Their manners of death were ruled a homicide, though a medical examiner for the defense testified Wednesday that he would have ruled their manners of death indeterminate.
Prosecutors said blood, DNA evidence and cell phone records will help prove Brown killed the women. Brown told police that he smoked marijuana with the women, had sex with some of them and passed out. When he awoke, they were dead.
Brown admitted to putting their bodies in cars and driving them to Detroit and pouring gasoline on two of the bodies in the trunk and setting it on fire.
