Psychotic Behavioral Profile
Previous Search & Rescue studies neglected
to describe subjects who became the target of search and rescue efforts
due to psychiatric problems. In the Virginia database this type of
search accounts for 5% of missing person searches reported. These subjects
suffer from psychotic disorders with schizophrenia the most common. Another example includes substance-induced psychotic disorders. Some
of the hallmarks of these disorders include delusions, hallucinations, and
disorganized behavior. |

Behavioral Profile
- Shape of distance traveled curve similar to Children (6-12)
- Fatality rates similar to Alzheimer's (22%)
- Many will not respond to name (93%), but may be verbal (21%)
- Some may be evasive
- Subject did not travel to identifiable target
- Often found in open woods (30%), structures (23%), or along roads (23%).
- Tend not to penetrate into thick brush/briars
- Large number of walk-outs (21%) and found along roads (14%)
- None got "lost" in traditional sense
- Lack of medications caused several searches
- Median distance from IPP 0.5 miles (0.8 km)
- Max Zone (92%) 4.8 miles (7.5 km)
- Law enforcement evaluation for searcher safety
- Consider limited field use of minors
Reflex Tasking
- Early use of trackers at initial planning point (IPP)
- Early use of tracking/trailing dogs at IPP or clues
- Through systematic search of residence, should be repeated throughout
search
- Investigation critical
- Early deployment of air-scent dog teams into woods and drainage's, start
near IPP
- Cut for sign along roadways and trails
- Team should stop and listen before shouting name if not contraindicated
- Subjects may flee, hide or move. Areas will need to be researched with
continual importance of looking for sign
- Subject may have a fear of authority, consider not wearing field uniforms
- Develop contingency plan if actively evasive (may require obtaining
emergency care order)
- Containment important along with road patrols
- Search urgency high
