Diego Maradona's lawyer Mario Baudry has blamed the doctors who were taking care of the Argentine's health for abandoning his former client.
The Argentina legend died at the age of 60 following a heart attack on Nov. 25, two weeks after being released from a hospital in Buenos Aires following successful brain surgery.
A doctor and a nurse coordinator are the latest individuals to be added to the investigation into the death of Diego Maradona, bringing the total to seven people.
Five other people, including neurosurgeon Leopoldo Luque and psychiatrist Agustina Cosachov, are already under investigation in the involuntary manslaughter probe.
Investigators are trying to determine whether or not there was negligence in Maradona's health care before he died.
A first autopsy conducted the day Maradona died found he had suffered from liquid on the lungs with acute heart failure brought on by a disease of the heart muscles that makes it harder to pump blood. His heart was twice the normal size.
Maradona is an idol to millions of Argentines after he inspired the South American country to only its second World Cup triumph in 1986.
