Lakeway police have wrapped up their investigation into the death of a 9-year-old girl who drowned at Lake Travis Friday morning. 

Police investigators say it appears it was just a tragic accident.

However the tragedy is far from over in the minds of many of the 12 to 15 police officers, paramedics and fire fighters who tried in vain to revive her.

"It seems to impact adults more to see a child die or suffer, or be severely injured," said Craig Campbell, a professor at St. Edward's University. Campbell offers courses for public servants, some of which include dealing with post traumatic stress disorder.

Campbell said most agencies do offer training in dealing with trauma, however he said there's a stigma attached to asking for help.

"A person wants for their superiors not to see them as being unfit for duty because of emotional reactions," said Campbell.

The professor also pointed out that since 1973 the average number of the nation's police officers killed in the line of duty has dropped from 134 to 34.  However the number of police officers who take their own lives nationwide has remained steady in the past 30 years, an average of 300 a year.

The City of Austin does offer free counseling for any of its public servants who need the service and they can remain anonymous.

"They're going to be more effective public servants, they’re going to be able to respond in an appropriate way," said Campbell.
