A Cobb County jail inmate was found unresponsive in his cell and died from an apparent aneurysm Saturday afternoon, officials said.

Jose Razo was rushed to Wellstar Kennestone Hospital after his cellmate noticed he was unresponsive. According to sheriff’s office spokesperson Randi Okray, the cellmate immediately called for help, prompting jail staff and medical personnel to perform life-saving measures.

After Razo was taken to the hospital, Okray said deputies contacted his family and escorted them to be with him. Razo died at the hospital shortly before 2 p.m.

Medical personnel said they believe Razo suffered an aneurysm. The Cobb Medical Examiner’s Office will conduct an autopsy.

Razo was booked into the jail Jan. 2 on charges of aggravated assault and willful obstruction of law enforcement officer, jail records show. He had received a bond of $27,720 but did not bond out.

Razo is at least the second inmate to die at the Cobb jail in the past few weeks. In November, Fernando Carr began suffering chest pains while in the recreation yard and later died at Kennestone Hospital. He had a documented heart condition and struggled with drug addiction, Okray said.

This year, the jail has seen at least two other deaths. Augustus Green died in an apparent suicide on Father’s Day, the sheriff’s office said. He was in a standard cell and had not expressed any suicidal thoughts, according to officials. In September, Raymond Marti suffered a seizure and was taken to Kennestone, where he was pronounced dead.

The GBI was asked to probe Razo’s death as the Cobb sheriff’s office conducts an internal investigation.
