A white, blood-stained blouse was found hanging in Michael Jackson’s wardrobe, femalefirst.co.uk reports.

The women’s garment — which still had its $3.99 price tag attached — was not seized as evidence by police officers investigating the singer’s death, despite legal experts speculating that it may have been used to mop up the singer’s blood, the website adds.

Lawyer Craig Silverman — who is not involved with the investigation — said: “It’s pretty extraordinary that a bloody shirt would not have been taken as evidence.”

A Los Angeles police spokesperson refused to say why the garment hadn’t been taken as possible evidence.

The spokesperson said: “I don’t know why it wasn’t taken. Our detectives aren’t speaking about the investigation so we won’t have an answer at the moment.”

Meanwhile, Jackson’s family has reportedly requested a third autopsy be carried out on the his body in order to prove foul play. Jackson was allegedly given the surgical anesthetic Propofol by his personal physician Dr. Conrad Murray earlier in the day to help him sleep.

A source said: “(His mother) Katherine looked at the second autopsy and she wasn’t happy with what it didn’t reveal to her.”

The Los Angeles County coroner’s office has not yet ruled on the cause of death, with results currently delayed indefinitely. Police are currently investigating Dr. Conrad Murray on accusations of manslaughter.
