View source for Yvonne Pearson - Yorkshire Ripper Victim

On the 21st January 1978 Yvonne Pearson, a convicted prostitute, was murdered by Peter Sutcliffe in Bradford. Her body was not discovered until the 26th March 1978 when it was found under an overturned  settee  on  wasteland  in  an  area  used by prostitutes.

In some ways this crime was dissimilar from those in the series so that, in a circulation to police forces on the 29th March 1978,  it was referred to as an independent case of murder not connected  with  those circulated  earlier. The main reason for excluding the case was that the head injuries appeared to have been caused by  a large stone rather than a hammer and that, additionally, death had been  due to injuries to the chest area, probably caused by her assailant jumping on her. 

Although her body was exposed, no stab wounds were inflicted. One unexplained factor was that a copy of the "Daily  Mirror" dated 21st February 1978 (exactly one month after she was last seen alive) was found under the right side of her body. This newspaper must have been intentionally placed under  the body and could  not have   been   in   that position  accidentally.	

The crime was investigated by [http://crimehub.co.uk/index.php?title=Detective_Chief_Superintendent_Lapish_-_Yorkshire_Ripper_Investigation Detective Chief Superintendent Lapish] of the Western Crime Area and another incident room was established at Bradford. Little evidence was forthcoming in connection with this crime, largely because of  the long  time  lapse  between  the  murder  and  the  discovery  of the body. There was, however, a different conclusion about the case when in May 1978 a West Yorkshire Police circulation linked it with other crimes in the Ripper series.
