(KMOV) -- A year and a half ago, a 19-year-old Florissant woman became the first female from Missouri to die during the Iraq war.

Private Lavena Johnson

The military was quick to point out that her death was not combat related.

Since then, her parents have struggled to find out what really happened to their daughter.

News 4’s Matt Sczesny took a close look at the evidence gathered by the military and asks the question, “was it murder or suicide?"

Among the thousands of graves at Jefferson Barracks cemetery there are stories of bravery, heroism, and proud service.

Among the thousands is the grave of Private Lavena Johnson, whose story is clouded in mystery and according to her parents, marred by murder and cover-up.

Lavena's father, Dr. John Johnson, has waged his own personal crusade to find out what really happened to his daughter in Iraq on July 19, 2005. 

The army ruled her death a suicide, the victim of a gunshot wound to the head.

In documents and autopsy photos obtained by the Johnson family and shared with News 4, more questions are raised than answered.

One strange fact was that Lavena was apparently abused, physically, and the autopsy didn't address the physical trauma to her body.

Military documents also show no apparent indication of suicide, her company commander wrote that Johnson was clearly happy and healthy physically and emotionally, something her mother knew by a phone conversation the day before she died.

Johnson's parents also question how their daughter at 5’1”, could handle a 40 inch M-16 to kill herself while sitting.

In fact, a military laboratory even concluded that based on a gunshot residue test, Johnson may not have even handled the weapon.

Additionally, Johnson's military debit card was never found, even though she used it two hours before her death to buy candy.

No bullet was ever found where she died, and a trail of blood is seen in photos outside the tent. Even stranger, it appears as if someone tried to set her body on fire.

So if it wasn't a suicide as the Army maintains, then how did Lavena Johnson die?

Based on the autopsy photos, her father believes that she was raped.

The military is unconvinced and consider the case closed.

A Pentagon spokesman says that the case was investigated thoroughly and that there is no evidence to reopen.

News 4 tried for weeks to get the Army to say more about the death of Private Johnson, but they're only response is that the investigation is closed.

Certainly the documents military investigators have gathered seem to say a lot more.

Johnson's father is now trying to have her body exhumed at Jefferson Barracks to have an independent autopsy performed.
