Washington- George Floyd died of low oxygen levels in the blood after former police officer Derek Chauvin pressed his knee against his neck for several minutes, said one of the witnesses in the trial of the former agent, doctor Martin Tobin, on Thursday.
Tobin is a lung and intensive care specialist who reviewed the medical records for this case.
During his appearance before a court in Minéapolis (Minnesota), Tobin explained that there are a number of reasons for the low oxygen levels found in Floyd’s blood. In that sense, he noted that Chauvin put 91.5 pounds, half the weight of his body plus that of his clothes and the equipment he was wearing, on Floyd’s neck.
“The cause of the low oxygen levels was weak breathing,” said the doctor, who explained that the air could not reach the victim’s lungs.
The expert, who relied on graphics and video images, stressed that the way in which Floyd was handcuffed and the position in which Chauvin pinned him to the ground created a kind of tourniquet that affected his breathing.
The trial against the former police officer began at the end of March. During the first days, the sessions of the process focused on the last moments of Floyd’s life on May 25, while this week experts and police experts testified.
The defense of the ex-agent is trying to link Floyd’s death to the fact that he used drugs, and his health problems.
Floyd was killed when four officers tried to arrest him for using a counterfeit bill to pay at a store. During his arrest, Chauvin pinned him to the ground by pressing his knee against his neck until he stopped breathing.
The former police officer is charged with second degree murder, punishable by up to 40 years in prison; murder in the third degree, with a maximum sentence of 25 years, and murder in the second degree, which carries up to 10 years of deprivation of liberty.
However, as he has no criminal record, he could only be sentenced to a maximum of 12 and a half years in prison for the first two charges and 4 years in prison for the third.
