BOSTON (CBS) – A Massachusetts State Police trooper helped make a young girl’s day after he tracked down her treasured stuffed bear that had fallen out her family’s car window.

On December 5, a young girl named Emma dropped Polar, her “lifelong companion,” out the car window and onto the travel lane of Interstate 495 in Milford.

“Emma started crying hysterically,” her mom Beth Deverix recalls, “and I said ‘what’s the matter?’ and she said ‘Polar’s out the window!’”

So she pulled over with hysterical child and called State Police.

“They asked if it was an emergency and I was very embarrassed to say ‘no it’s not an emergency my daughter lost her lovey,’” Deverix said.

Deverix admits she would have understood if police had declined the stuffed bear rescue — but that didn’t happen.

Trooper Dan Mather, a father himself, responded and understood the urgency. He hunted the bear down in traffic and found it on the rumble strip by the left hand lane.

“Anyone with a child that has ‘that one’ thing that they bring everywhere with them, knows how traumatic this would be to a small child,” police said on Facebook.

Emma and her parents wrote a thank you note to Mather for helping them.

“We appreciate what you did and your kindness – you made one little girl so very happy to be united with her lovey. Thank you so much,” the note said.

State Police said the card from Emma “made Trooper Mather’s day.”
