KILLEEN, Texas – The disappearance of Vanessa Guillen exactly one month ago has loved ones asking questions.

Roughly 50 family and friends gathered in Killeen Friday to make signs and noise for a peaceful protest. They formed a convoy and drove together to the Mayborn Gate at Fort Hood.

Guillen’s mother tearfully pleaded for answers, and her sister says the investigation is a joke and they feel slighted by the Army.

No one has heard from Vanessa since April 22, and the family has no leads on her whereabouts.

FOX 44 contacted Fort Hood’s Criminal Investigation Division but they said they could not discuss any details of active cases and investigations.
