A new method for locating saliva stains-spotty paper for spotting spit.

A convenient method of locating saliva stains has been devised. Filter paper covered with blue coloured starch fragments is laid on the material to be tested. Salivary amylase hydrolyses the starch on the areas of paper corresponding to saliva stains, which are then delineated as clear zones whereas negative areas remain speckled with blue particles.

Sexual assault patterns.

The numbers and types of all sexual offences examined at the Metropolitan Police Forensic Science Laboratory during the years 1978-1986 are presented. The largest number of sexual assaults took place during the month of August; they were mainly intra-racial and between adults of 18 to 30 years of age. A detailed breakdown is given of the offences against females recorded on the Sexual Assault Index. All these assaults were carried out by adult males, mainly strangers. Nearly half the assaults took place indoors, where victims were more likely to be bound and blindfolded, compared with one-third outdoors and one-sixth in vehicles. About one-fifth of the crimes were carried out by two men or more, and in one-third of cases, weapons were carried. Oral intercourse occurred in one-sixth and anal intercourse in one-twelfth of the offences, both performed more by white males and those of Mediterranean origin.
