(Lara Fominoff/650 CKOM) When Jean Romero’s son began complaining of headaches Thursday, she told him to take a Tylenol. Then when her daughter, who’s taking university classes online, also told her mom she wasn’t feeling well, Romero asked her to open a window. She never thought for a second that her children might be suffering from carbon monoxide poisoning. Romero, her husband and their two children live on the second floor of a Saskatoon apartment building in the Greystone Heights area that was the site of a carbon monoxide leak Thursday night.
