   Metro police responded to the 9900 block of Plaudit Way on Wednesday morning after a family member found the three in the family's garage.

   Investigators believe the father turned on the car to warm it up while it was in the garage and that all three people were poisoned by carbon monoxide. 
   
   "This could happen very, very quickly, and it did, in this case," LMPD Lt. Emily McKinley said. 
   
   The three were found by a family member, who called 911. 
   
   When first responders arrived, they found all three unresponsive in the closed garage. 
   
   Juvenal Garcia Mora, 39, and Cruz Isaac Garcia, 3, were pronounced dead in the emergency room at the Medical Center Jewish Southwest. Their causes and manners of death are pending. 
   
   Police closed down streets and escorted an ambulance carrying a 7-year-old girl to Norton Children's Hospital. The girl was last said to be in critical condition. 
   
   McKinley said police hope the tragedy will serve as a reminder to people of the dangers of carbon monoxide. 
   
   
   
   “I know it's the winter months and everyone wants a warm car to get into, but be cautious of the areas and make sure it's a well-ventilated area, because horrible accidents happen like this, and they happen very quickly,” she said. 
   
   The mother of the two children was not home at the time of the incident, but police have notified her. 
   
   McKinley said they don't have reason to believe the incident was anything other than a tragic accident, but they are still investigating the deaths. 
   
   Carbon monoxide is a colorless, odorless and tasteless gas. 
   
   It's lighter than air and spreads quickly. 
   
   Symptoms of carbon monoxide poisoning often mimic the flu -- and include headaches, nausea and dizziness. 
   
   In high concentrations, carbon monoxide can be deadly in less than five minutes.

target: – A heartbreaking story out of Kentucky, where a father and his 3-year-old son died of apparent carbon monoxide poisoning Wednesday morning; the man's 7-year-old daughter is in critical condition. Juvenal Garcia Mora, 39, was found unresponsive inside his garage but not in his car; the children were inside the car. "It appeared to be that he had warmed the car up while it was in the garage, and trying to get the kids out the door to school and start the day," a police rep tells Fox 19. The children's mother had already left for work at the time. Relatives, concerned when Mora didn't show up at work and his daughter didn't arrive at school, went to the house and then called police. The police rep, who said the situation appears to be a "horrific accident," notes that it's a sad "reminder in the cold months to be cautious of running vehicles inside of closed, indoor areas, specifically garages," as that can lead to carbon monoxide poisoning. In high concentrations, the colorless, odorless, tasteless gas can be fatal in five minutes, WLKY reports. "This could happen very, very quickly, and it did, in this case," the police rep says. (Carbon monoxide was also suspected in the deaths of six teens in a garden shed.)
