BATON ROUGE, La. (AP) — The East Baton Rouge Parish coroner says preliminary autopsy results show complications from an enlarged heart killed a man who died while fighting with four Baton Rouge police officers.

Dr. Beau Clark tells The Advocate final autopsy results for 43-year-old Derrick Dukes will depend on the outcome of toxicology tests, which should be ready in four to six weeks.

Clark says the results will help him determine whether Dukes' heart complications were natural, induced by drugs or both.

Dukes died just before 1 a.m. Friday at an area hospital. Dukes was taken to the hospital after he stopped breathing during a fight with police officers.

Cpl. L'Jean McKneely said the fight began after police were called to Dukes' home in reference to a domestic dispute.
