Doctors evaluating accused serial killer Ryan Sharpe have until July 23 to determine whether he was sane when he allegedly killed three men and wounded another in four separate shootings in East Baton Rouge and East Feliciana parishes in 2017, a judge decided Tuesday.

The doctors' reports were originally due two weeks ago so that a sanity hearing could be held Tuesday in Baton Rouge, but retired state District Judge Bruce Bennett was told the doctors needed more information and time to complete their reports.

Sharpe, 37, is charged in East Baton Rouge with second-degree murder in the September 2017 slaying of former BREC commissioner Carroll Breeden Sr., 66.

In East Feliciana, Sharpe is charged with second-degree murder in the July 2017 killing of Thomas Bass, 62, and first-degree murder in the October 2017 shooting death of Brad DeFranceschi, 48. He's also charged with attempted first-degree murder in the September 2017 wounding of Buck Hornsby.

Sharpe, of Clinton, already has been declared competent to stand trial by judges in both parishes. Those rulings came in March.

He has pleaded not guilty and not guilty by reason of insanity to all four charges against him.

Sharpe’s attorney, Tommy Damico, said Tuesday that whether someone is not guilty by reason of insanity is a factual issue that a jury would decide.

Sharpe told investigators the killings were intended to fill hunting "tags" issued to him by the government, according to an East Feliciana Parish Sheriff's Office report.

Sharpe also said he had other tags that hadn’t been filled when he was arrested in October 2017, the report states. He called police and identified himself as the shooter, authorities have said.

Doctors have reported that Sharpe remembers nothing of the events, which all took place within a 25-mile radius of Clinton, Damico has said.

If a jury finds Sharpe not guilty by reason of insanity, Damico added, he would be civilly committed and would not be subject to any criminal penalties.

Sharpe’s alleged victims were either working or walking on their properties near the road when they were shot.

Bass was killed outside his La. 960 residence; Breeden was slain outside his home on Pride-Port Hudson Road; DeFranceschi was gunned down outside his home on the Avondale Scout Reservation on La. 63; and Hornsby was wounded outside his residence close to La. 63.
