Years after Greg Fleniken's death, the case continued appearing in magazines, television programs, podcasts and true-crime discussions.
It had all the ingredients of a classic impossible mystery.
A locked room.
A dead man.
No blood.
No weapon.
No intruder.
Money untouched.
A strange autopsy.
Then the reveal.
The fatal force did not enter through the door.
It came through the wall.
But the deeper story is not really about a clever mystery.
It is about how investigators think.
And how easily a wrong assumption can hide a simple answer.
Room 348 seemed impossible only because everyone initially imagined that the fatal event had to happen entirely inside Room 348.
Once investigators allowed themselves to ask what might have entered from outside the room, the puzzle collapsed.
The door being locked was no longer strange.
Of course it was locked.
Greg was alone.
The lack of disorder made sense.
Of course there was no struggle.
There was no attacker inside.
The untouched money made sense.
Nobody came for the money.
The absence of a conventional gunshot wound made sense once the unusual entrance location was recognized.
The internal injuries made sense once the bullet path was reconstructed.
The neighboring room made sense.
The hidden hole made sense.
And Greg's final movements made sense.
He had been sitting on the bed.
Probably comfortable.
Movie playing.
Candy nearby.
Cigarette burning.
Then a round passed through the wall.
It struck him without warning.
He stood.
Perhaps he did not immediately understand what had happened.
Perhaps he thought something inside his body had ruptured.
Perhaps he tried to reach the hallway.
The door was only a few feet away.
He fell before reaching it.
On the other side of the wall, the men confronted an entirely different scene.
A gun had fired.
Nobody in Room 349 appeared hit.
Then they saw the wall.
A bullet had gone somewhere.
At that exact moment, the case could have ended differently.
Knock.
Open the connecting door.
Call the front desk.
Dial 911.
Say:
We accidentally fired a handgun through the wall.
Instead:
Hide it.
Toothpaste.
Toilet paper.
Get rid of the weapon.
Say nothing.
Then wait.
The following morning police arrive.
The neighboring guest is dead.
Still say nothing.
Investigators ask questions.
Still say nothing.
Months pass.
A widow wonders who murdered her husband.
Still say nothing.
That is why the title "accidental shooting" never fully captures what happened.
The discharge may have been accidental.
The silence was sustained.
The mystery was manufactured.
Greg's ordinary habits ended up becoming important clues.
He smoked with his right hand.
The cigarette was in his left.
He preferred rooms extremely cold.
Room 348 was warm.
He kept his belongings neatly arranged on a towel.
They remained undisturbed.
Each one said the same thing.
Something happened suddenly.
Right there.
He had not spent the night fighting an enemy.
He had not returned from some secret confrontation.
His ordinary evening had been interrupted in a fraction of a second.
And one of the reasons the case eventually became solvable was that Susie knew her husband well enough to recognize those tiny deviations.
The investigators knew the physical room.
Susie knew Greg.
Both forms of knowledge mattered.
Then Brennan supplied the connecting question.
What is on the other side of that wall?
It is a deceptively simple question.
But detectives often solve cases through simple questions asked at the right moment.
Not every breakthrough is DNA.
Not every breakthrough is an anonymous confession.
Not every breakthrough is sophisticated software.
Sometimes it is a dent in drywall.
Sometimes it is a door handle that misses the dent.
Sometimes it is toothpaste where toothpaste should never be.
And sometimes it is a laser beam crossing two hotel rooms and pointing directly toward the place a dead man had been sitting.
That laser changed the case from impossible to obvious.
It gave the room geometry.
The body gave the trajectory.
The men in 349 gave the final explanation.
The investigation that had once seemed to require a hidden murderer ultimately revealed something much less elaborate.
Greg Fleniken was not targeted.
He was not chosen.
Nobody had planned his death.
He was simply on the other side of a wall when a loaded handgun was handled recklessly.
That randomness may be more frightening than intention.
A targeted victim can sometimes recognize danger.
A random victim cannot.
Greg could not know there was a gun next door.
He could not know it was pointed toward the shared wall.
He could not know the people handling it had been drinking.
He could not know the bullet was coming.
His room was locked.
And that was not enough.
Return one final time to September 15, 2010.
Room 348.
Greg sits on the bed.
Iron Man 2 playing.
Root beer.
Reese's candy.
Cigarettes.
His phone nearby.
On the other side of the wall, men are drinking.
A Ruger appears.
Someone handles it recklessly.
The weapon swings.
A shot.
The bullet tears through the drywall.
Crosses the tiny space between two hotel rooms.
Strikes Greg.
He rises.
Moves toward the door.
Falls.
The cigarette remains in his hand.
The television keeps playing.
The room warms.
Behind the wall, someone stares at a hole.
They cover it with toothpaste.
Hours later, Greg's coworkers knock.
Nobody answers.
Hotel staff defeat the security latch.
The body is found.
Police enter.
The money is there.
The laptop is there.
No killer.
No obvious wound.
No explanation.
For months, detectives search everywhere except through the wall.
Then Ken Brennan notices one small dent.
He opens the connecting door.
The handle does not touch it.
He walks into Room 349.
There is the patched hole.
The wall is opened.
A laser is switched on.
The beam travels straight through the hotel wall and into Room 348.
Toward Greg's bed.
And in that instant, the locked-room mystery disappears.
Because the door had never mattered.
The killer was never hiding inside Room 348.
The answer had been on the other side of the wall the entire time.
