Heavy B767 was landing roll Runway 25L; an A320 was emergency aircraft inbound 7 miles in trail of the Heavy B767; however the A320 was landing inboard Runway 25R. Subsequent aircraft an E135 was behind the A320 on a Visual Approach Runway 25L. The A320 landed without incident regarding emergency status; however the wake turbulence minima (5 miles) was not adhered to. I was unaware at the time of this scenario unfolded that separation was lost. Subsequently; I was told later that there was more then 4 but less then 5 miles with A320 landing behind B767. The role I played was that the emergency aircraft land and not be sent around. In hindsight; the Heavy; lead aircraft; should have been taken off the approach to avoid any conflict or question as to spacing regarding wake turbulence. This is a task I've performed numerous times without incident.
TRACON Controller described a loss of heavy separation when an emergency aircraft landed on a parallel runway without the required separation.
