A 23-year-old man who was in custody of the Jim Wells County jail died Thursday evening after a correctional officer found him unresponsive, according to JWC Sheriff Daniel Bueno.

Marcus Soza was arrested on Wednesday, Jan. 31 for manufacturing and delivery of a controlled substance during a traffic stop.

On Thursday, Feb. 1 at approximately 11:22 p.m., a security check was conducted. The correctional officer came upon Soza unresponsive, according to the Sheriff. He was alone in his holding cell. According to the sheriff, jailers conduct security checks every 30 minutes per policy.
