Tyler Mollner's nearly 3-year-old son, Stephen, dumped a bottle of body spray in the room of his 16-month-old sister Oceania. Tara Karr, Mollner's fiancee, thought the perfume was out of their daughter's reach, but somehow Oceania ingested some of the spilled spray.

When the couple got their daughter up, they knew immediately that something was horribly wrong.

"(It was) sheer terror, panic — what could I do? What could I have done?" Mollner remembered thinking. "I called out for Tara and she told me to take her straight to the ER."

With no time to wait for an ambulance, Mollner rushed his daughter to the emergency room.

Karr said hospital staff called a code blue when her daughter and fiance arrived. Oceania was limp in Mollner's arms and had difficulty remaining conscious. Her heart rate had dropped and her breathing rate was eight times per minute where it should have been around 20 or 25, Karr said.

Doctors sedated Oceania and put her on a breathing tube. She then fell into a coma. Karr and Mollner would later learn that their daughter had consumed isopropyl alcohol that was in the perfume.

When his daughter emerged from the coma four hours later, Mollner prepared to return home.

Then, another piece of bad news: Mollner's car had a flat tire and security needed to have his vehicle moved.

But a stranger came from nowhere and offered to replace the tire.

At first, Mollner denied the generous offer because he had a spare in the trunk. But after some convincing, he agreed to let the woman help.

"She paused and goes: 'you know what, I'm just going to buy you a full set of tires. You're dealing with enough stress and everything going on right now you don't need this on top of it,' " Mollner remembered.

The woman took his vehicle to a car shop across the street and bought him four brand new tires.

But in all the commotion, Mollner forgot to get the woman's name. Now, he hopes to find out who she is.

"I'd like to speak to her in person, give her a thank you card and try to pay her back. I really would," he said.

Mollner asks that the person who helped reach out to him directly on Facebook.
