Vanessa Guillen's sister doesn't believe official account that soldier was killed in Fort Hood armory room, says more people may have been involved, and slams evidence in the case as 'sketchy'

Murdered Fort Hood soldier Vanessa Guillen’s sister is speaking out saying she doesn’t believe her sister was murdered in the armory room of the Texas base as officials claim.

Myra Guillen opened up on her heartbreak on losing her sister who went missing from the Killeen base on April 22 and whose dismembered remains were found three months later on June 30.

Guillen had vanished after telling her family she was sexually harassed at the base, however, officials have denied any connection between the claim and her death. 

'Honestly, in my heart, I don’t believe that it happened in the arms room. I don’t feel like that’s the real story,' Myra said in a special called 'A Fort Hood Investigation with Nancy Grace' that will air on Fox Nation.

Vanessa Guillen's sister Myra Guillen says she doesn't believe her sister was murdered in the armory room of the Fort Hood Army base as officials claim. She said: 'Honestly, in my heart, I don’t believe that it happened in the arms room. I don’t feel like that’s the real story'

Vanessa Guillen, 20, went missing from Fort Hood on April 22 and her dismembered remains were found three months later on June 30

Myra says Vanessa’s boyfriend last tried to contact her at 11am and he got no reply, leading Myra and her family to suspect that Vanessa was dead by that time. 

'It’s so, so sketchy because they say he clocked out at 11.40am. What makes me think he can do everything in 40 minutes from picking her up, cleaning up, and everything? There’s no way,' she added. 

When Vanessa disappeared investigators said she left behind her car keys, room key, ID and wallet in the armory room - but Myra says that's unlike her sister and she would never leave those things behind. 

A federal complaint released July 2 identified 20-year-old soldier Specialist Aaron Robinson as her killer. 

Myra said she suspects Robinson knocked her sister was knocked unconscious then took her elsewhere to kill her. 

'I believe she was taken unconscious. There’s no telling where he might have went or with who. I don’t know if it was just him and Aguilar or if there’s more people to this, which I strongly believe there is,' Myra said in the interview.

Host Grace responded: 'I see what you’re saying Myra. Because they’re in the armory room in broad daylight. Nobody saw anything? Nobody knew anything? Is it possible they were the only two at work? I don’t think so.'

A federal complaint released July 2 identified 20-year-old soldier Specialist Aaron Robinson as her killer. The complaint said he killed Guillen by hitting her in the head with a hammer and he enlisted the help of his girlfriend Cecily Aguilar to help dispose of her remains

Investigators who searched Guillen's phone said the last person she texted was Specialist Robinson.

The complaint, filed at the U.S. District Court Western District of Texas, said he killed her by striking her in the head with a hammer while on the base. 

He then transferred her body off the base to a remote area where he enlisted the help of his girlfriend Cecily Aguilar, 22, of Killeen to dispose of her body, burying her body parts in several graves close to the Leon River about 25 miles from Fort Hood, according to the complaint.

He shot and killed himself as police honed in on him. 

Aguilar was arrested and charged with conspiracy to tamper with evidence. 

Family members say that Robinson had been sexually harassing Guillen and once watched her while she showered.

Robinson, a 20-year-old soldier from Calumet City, Illinois who was deployed to Iraq for seven months in 2018, was a specialist ranked above Guillen, a private first class, at the time. 

However, Former Fort Hood senior commander Maj. Gen. Scott Efflandt, who has since been reassigned, said there was no connection between sexual harassment and her disappearance.

This year alone there have been 28 deaths at Fort Hood base in Killeen, Texas including five homicides and eight suicides

'In our criminal investigation, we found no evidence of sexual harassment between Vanessa and Spc. Robinson…That was ruled out very early,' Maj. Gen. Donna Martin, who leads the Army’s Criminal Investigation Command, said in an ABC's 20/20 interview last month.

Today the harsh spotlight over Fort Hood has only intensified as a slew of soldiers have disappeared or died at the base, triggering multiple investigations into the command culture, the base's handling of deaths missing cases and sexual assault reports.

This year alone there have been 28 deaths at Fort Hood base in Killeen, Texas including five homicides and eight suicides. 

'A total lack of transparency. A mountain of glaring evidence exposing undeniable negligence at America’s single largest military base,' Grace said. 

In September, the I Am Vanessa Guillen bill was introduced in the House of Representatives that will change the way the Army handles reports of sexual harassment and abuse.
