Diego Maradona's doctor being investigated after soccer legend's death

Argentina soccer legend Diego Maradona died on Wednesday at the age of 60 after suffering a heart attack. While he did have a number of health problems that could have led to his death, Maradona's doctor now has become the center of a criminal investigation. 

According to TMZ Sports, police searched the office and home of Dr. Leopoldo Luque after several witnesses said they had seen him and Maradona fighting and shoving before his death. Police also are interested in Luque because he allowed Maradona to leave the hospital just eight days after having surgery for a blood clot in his brain earlier this month. 

Maradona's death was ruled a "culpable homicide," which means killing or causing someone's death unintentionally. The probe of Maradona's doctor involves allegations of negligence, TMZ adds, and he could be charged if there is evidence that he caused the legend's death. 

Maradona's family "strongly believes" his death was a homicide and demanded an investigation into Luque.

Maradona is considered one of the best soccer players to ever take the field. He led Argentina to a World Cup title in 1986 and won the Serie A title during the 1986-87 and 1989-90 seasons.
