Death: Getting it Right

The guy in the black clothing sneaks up behind his victim, slips his large hands around her throat and squeezes.
She desperately reaches for her throat, weakens and drops dead.
The teenager is dead on the pavement, blood gushing from the hole in his chest.
A masked man walks into a convenience store, whips our a nine-millimeter handgun and shoots the woman who tries to stop him, blowing her head off.
I cringe.
I don't want to read these novels anymore.
I don't stop because the scenes are frightening, shocking or gross.
I can handle that.
I stop because I have lost my suspension of disbelief.
The death scenes are impossible.
Inaccurate.
Unreal.
It takes about five minutes to die from asphyxiation and it's a messy death, with the victim in panic mode, fighting with huge doses of previously unknown adrenaline for his or her life.
Hearts stop beating when people die, so blood stops flowing.
Nine-millimeter bullets might make small messes inside their targets, but not outside.
They certainly don't blow heads off.
I don't want to be that writer -- the writer who loses readers who are familiar with guns, medicine or death.
And it's amazing how many people know that stuff.
That's why I appreciate people like D.P Lyle.
I met D.P. Lyle in August at Killer Nashville, a conference for mystery writers in Nashville, Tennessee.
I listened to him speak, chatted with him, bought two of his books and became a fan of his blog and podcast, Crime & Science Radio.
Dr. Lyle is a cardiologist, a novelist, a writer of nonfiction and a medical consultant for authors. He has worked as a consultant for such television shows as Law & Order, CSI: Miami, Diagnosis Murder, Monk, Judging Amy, Peacemakers, Cold Case, House, Medium, Women’s Murder Club, 1-800-Missing, The Glades, and Pretty Little Liars.
His expertise is a big part of the reason I attended Killer Nashville, to improve my knowledge of forensics.
To get it right for my own peace of mind and for readers.
Every mystery writer needs a D.P. Lyle.
Who is yours?
