'We still hurt': Jermaine Jackson says his family are angry that his late brother's physician Conrad Murray is being released early from jail this month

Jermaine Jackson says his famous family has been left outraged over the early prison release of the doctor convicted of involuntary manslaughter in the death of his pop superstar brother Michael.

The 58-year-old singer says he is furious over the scheduled release of Dr. Conrad Murray later this month.

Murray was convicted of involuntary manslaughter and sentenced to four years in prison in November 2011 for his role in the 2009 death of Michael Jackson.

Jermaine told TMZ that his family is more upset about Murray's scheduled early release on Oct. 28 than they are about mother Katherine Jackson's recent loss to concert promoter AEG Live in her wrongful death lawsuit.

'The most important thing right now is that we let the world know how we feel about his verdict because somebody's doing business,' Jermaine said.

'It's not about the money. This guy is walking this month. He's walking free this month. So you kill Michael Jackson and you're out in two years, it sucks. We hurt. We still hurt,' Jermaine added.

'We're very strong people, but we're humans,' Jermaine said.

Murray's sentence was recently reduced to two years due to his good behaviour and jail overcrowding.

Jermaine bought a Ferrari for $160,000 the day before a jury decided that concert promoters AEG Live were not responsible for the Thriller hitmaker's death from acute propofol intoxication.

Jermaine dismissed reports suggesting his mother was furious about his lavish purchase.

'My mother is not upset,' the singer said.

It was recently reported that Katherine had to bail Jermaine out of debt and help him pay his child support payments.
