As a semi-related side note regarding the Valley Division (Van Nuys) :
When the Tele-Type was sent out in circa Sept 1969 from Downtown (forgot the division's proper name at the moment...) to all of the other LAPD divisions in regard to the gun found in a back yard around the neighbourhood where the Sharon Tate ,et al. , murders took place , there was an oversight : ALL divisions were sent the Tele-Type except the Valley Division ; they had the ".22 Longhorn Special " in their evidence room !
Apparently , the officers whom retrieved the .22 from the parents of the kid whom found the gun , decided to just put it in the evidence locker and forget about it !
" ... be sure to ascertain whether your division has the item in question [...] as soon as you [find the .22 Longhorn] please call area code (213) MAdison-56885 . ..."
