Luisa Carrillo is the high school girl who jumped out of the moving during the frightening hijacking of a bus by Guatemalan bandits armed with a gun and a grenade. On Friday, it was heralded as encouraging news that she had awakened from an induced coma. On Saturday, the prognosis seemed even better when she started to speak. But on Sunday she slipped into a coma and showed signs of significant brain swelling. Hours later, she was dead.

Today, her doctor Joel Cervantez commented on the unexpected turn of events after taking Luisa out of the induced coma.

"Basically because we did control brain CT scans that show that the amount of swelling had gone down significantly. Also, we monitored the vital signs on a continuous 24-hour basis. Before we had needed to use certain medications to keep them within artificial range. The first 24-48 hours. By Friday, once we had already taken her off the machine, those medications were not necessary. That is why we felt comfortable to wake her up. And she responded well. If she hadn't responded well we'd have had the necessity immediately to put her back on the machine. That was Friday late in the afternoon. She evolved well Friday night. She had some liquids to drink. Saturday, she started to take a soft diet. She was a bit more responsive with family members. Not having long conversations but short conversations. And Sunday morning I spoke to her early, a couple minutes after 7AM and she gave short answers that she had done on Saturday. She referred that she was sleepy, that she wanted to sleep. Approximately about 8:45AM, I got a call from the nurse saying that the patient was unresponsive. We checked her and realized that she had just suffered an acute event. Suspecting that several things could have happened -- perhaps a stroke, a resurgence of brain swelling or a combination of both factors. We did a brain CT scan and what the evidence was that around the brain stem, the most primitive part of the brain, the water canals that surrounded, yes, there was the appearance of blood that wasn't there before. Basically what this did was shut down the supply of blood to the brain. And at the same time that causes brain enema to resurge. So she already had some residual blood brain swelling but with this new appearance, that sent the brain into overdrive because then the necessity became to have to make space so her brain could swell out which is the next step that we did that same day. We took her to surgery and did extensive removal of bone, bone flap, taking off bone to allow the brain tissue to swell out. Severe brain injuries like these you can have people having improvements, go a couple steps forward and then go a couple steps backwards. So you have to be very cautious with patients like these. That explains why you don't discharge a patient like this very soon because you have to be very observant and because in most patients under these conditions, it takes about two to three weeks before really acute problems – brain swelling and bleeds within the brain-- can be resolved, with or without surgery."

The surgery was conducted on Sunday, but Luisa passed away at 1:10 Monday morning. 7News met the parents and the rest of Luisa's family at the KHMH, waiting for the results of a post mortem today.

Her parents, brothers and sisters were too distraught to speak with us, but her cousin, Sylvia Carillo told us how the family was trying to deal with the death of their loved one.

"The family, all of us, we're just trying get together and be there for each other, support each other, but my uncle and my aunt they're really finding it hard to cope with it but they're pulling through it."

Jim McFadzean,
"When Luisa was taken out of the coma, did any of you get a chance to speak with her?"

Sylvia Carillo, Cousin of Luisa Carrillo
"My cousin Sandra did. She is her sister. I was here Friday. She was waking up a bit, moving around. The only thing she said on Friday was, "Where is my mom?" On Saturday, she started speaking a bit more. And she spoke with my cousin Sandra again and she said, "Where are my parents?" She asked for food and they gave her food to eat. They took her out of the ICU then. Later, Saturday night, early Sunday morning, she started complaining about a headache and they had to rush her back in the ICU for immediate surgery."

Jim McFadzean,
"Did you get the impression from your cousin that she had recognized your cousin during the brief time that she spoke with your cousin asking for her mother?"

Sylvia Carillo, Cousin of Luisa Carrillo
"Yes, yes, she did. She recognized all of them. Even Friday, a close friend of the family went to see her and her eyes were not open but she was talking to her and touching her and she asked her, "Do you know who I am?" And she said, "Yes." So she knew people. She knew her family. Yeah."

Jim McFadzean,
"One would think that the family's hopes were really high at the point, am I right?"

Sylvia Carillo, Cousin of Luisa Carrillo
"Yes, Friday, we were all happy. We saw a big difference in her and her features as well. On Saturday, we were more than hopeful. But when we heard the news that she was rushed in immediate surgery, we started panicking."

19 year old Luisa was scheduled to graduate from Sacred Heart High School in June of this year. She is survived by her parents, four sisters and three brothers. Funeral arrangements are tentatively set for this Thursday in the village of Succotz.
