Here is a link to study carried out at the Finnish National Bureau of Investigation into strangulation and offender profiling.
It depends on whether the strangulation was by ligature or by hand or arm.
A few points of interest -
Strangulation accounts for 10-20% of all homicidal deaths in various countries
It "may be" due to the positions of the murderer and victim [...] which makes it easy and convenient and prevents victim from crying out
In 59 strangulation cases (focus of study) -
Very interesting indeed, somewhat surprised by some of the statistics like 72% intoxicated and the high number ( 45.8%) of people strangled by acquaintances.
For obvious reasons, posting your link in the Barry and Honey Sherman thread, thanks.
Average victim age was 35.6 years
Average age of offender was 34.11 years
stranger 1% - manual
family member 25% - manual 80% ligature 20%
ex-intimate 27.1% - manual 75% ligature 25%
acquaintance 45.8% - manual 51.9% ligature 48.1%
15% of offenders were psychotic
61% of offenders had a personality disorder
12% of offenders had some other disorder (depression etc)
12% of offenders no mental illness
66% of offenders had alcohol dependence
14% of offenders had drug dependence
At time of murder - 72% of offenders were intoxicated and 10% were under influence of drugs

The report goes into further detail but I don't have the time to paraphrase it all - it's interesting.
