NASHVILLE, Tenn. (WKRN) – A Massachusetts woman got quite a shock when police pulled her over on Monday, but instead of a warning or a ticket, she got a reunion with her son, a U.S. soldier.

Darlene MacAllister had that sinking feeling as she saw blue lights flashing behind her.

“I was scared. Like, what did I do wrong? I know I was speeding a little bit trying to get home,” she recalled.

Not one but three police officers pulled her over, politely telling her to get out of her car. The officers then asked multiple questions.

“’What’s up with your sticker? When did you get that? When did you get that?’” MacAllister explained. “What he was doing was distracting me.”

The distraction was so her teenage-son-turned-soldier, Alan, could pull off the surprise homecoming he’d been plotting for weeks.

“It definitely caught me off guard because I just had hung up with him, saying he wasn’t going to be home because his flight was cancelled,” the mother said.

Alan, an army engineer based at Fort Carson, Colorado, said the look on his mother’s face was priceless.

“I can’t explain it. It was one of those looks like you’re so happy but so pissed off at the same time,” Alan said. “But yeah, I got her!”

Both Alan and his mom plan to re-connect with family over the Fourth of July holiday and celebrate his 19th birthday.

MacAllister is also making it no secret: one good prank deserves another.
