Kevin Sweat is being held in the Seminole County jail on a murder charge in connection with the death of his girlfriend, Ashley Taylor, 23.
According to court records, charred remains believed to be those of Ashley Taylor were found Aug. 4 on a farm belonging to Sweat's father.
Wayne Woodyard, Kevin Sweat's attorney in the Ashley Taylor case, said he could not comment about whether his client has been questioned in the Weleetka case.
“The concern we have in reference to the Taylor case is the more of that speculation that is done on the Weleetka case, the harder that is going to be to get a fair trial in the Taylor case,” Woodyard said this month.
