The parents of slain soldier Vanessa Guillen met with President Donald Trump on Thursday and pleaded justice for their daughter. Trump then vowed to help the 20-year-old's parents find justice.

Speaking through an interpreter at the White House, Pfc. Vanessa's mother, Gloria Guillen, tearfully pleaded for justice for her daughter, who was brutally murdered in Fort Hood last April.

Gloria asked Trump to help them investigate the death of her daughter, who was reportedly battered to death using a hammer in an armory room on the Texas military base, where she was assigned.

Her family said Vanessa was supposed to file a sexual harassment report against her fellow soldier, according to a CNN News report.

Gloria told Trump that she wanted to know, who was really responsible for her daugther's death. She also said her daughter died in service of her country and at the hand of people in the military. Vanessa's family asked reforms within the rank.

For his part, Trump said Vanessa's death hit him "very hard." Trump described the soldier as a "spectacular person, respected and loved by everybody, including in the military."

Trump told Gloria, her husband, and their two other daughters that the Federal Bureau of Investigation (FBI) and the Justice Department "are now involved" in the investigation. He also noted that people at the Fort Hood are also "very much involved" in the probe. Trump promised to look into the death of Vanessa.

"You have our support, and we're working on it already, as you know, and we won't stop, and hopefully something very positive will come out in honor of your sister," the president said.

Meanwhile, Family attorney Natalie Khawam questioned how no one heard Vanessa screaming and how no one saw her blood. She also said the killer used a machete to cut her up and even tried to burn her body. The lawyer added that it reminded her of ISIS and how they brutally killed American soldiers.

During the meeting, Trump was asked by a reporter on what he can particularly do to help the grieving family of Vanessa. He said he would shoulder Vanessa's funeral expenses just like what he did to other soldiers.

"I don't even know if you need help, maybe you don't need help from a financial standpoint. I have no idea. I just think it's a horrific thing that happened and if you did need help, I'll be there to help you," the president said.

Vanessa's family has declined to have a military funeral. They said that right now, they are just waiting for Vanessa's remains. Trump then promised to speed up the travel of the soldier's remains that were found on July 2 following her disappearance in April from Fort Hood.

The family has also asked Trump to ask support for the #IAmVanessaGuillen bill that calls all active-duty service members to file sexual harassment claims through an independent army.

According to The New York Post report, the U.S. Army said one of the suspects has committed suicide by shooting himself with a pistol when police confronted him near the Texas base.

On Thursday, the Army has released the names of five civilians, who will review the command and climate culture at Fort Hood for possible abuse in any form.
