I believe that Inspector Frederick Abberline is seated in the front row, center (sixth one from the left). If you look closely, you can see the letter "A", written upside down, in blue paint or ink right in front of that officer too. I am not sure if the letter was painted on the ground prior to the photo shoot or if the letter was added in ink directly to the photograph itself, by a family member or friend of the family.
