BACHELOR Sean Lowe dodged a bullet when he sent AshLee Frazier packing!

The ENQUIRER has learned the bubbly pastor’s daughter was hiding a big family secret – her sister and brother-in-law have criminal pasts.

The 32-year-old beauty and Sean were brought together by their shared deep Christian faith. But, in the end, AshLee failed to win Sean’s heart, and an insider believes that’s a good thing.

“I THINK ASHLEE’S FAMILY IS nuts,” the insider said. “Her little sister Heather is a con­victed criminal and Heather’s husband is a convicted felon!”

The ENQUIRER has obtained court and police records that detail the extensive criminal records of Heather and her husband Michael Alan Baker.

According to authorities, Heather was arrested for breaking into a vehicle in 2006. The case was dismissed after she paid restitution, but in 2007 she was convicted of theft after stealing a Target gift card and spent 22 days in jail.

In 2008, she was busted for allegedly making a false police report. The charges were later reduced to disorderly conduct.

Heather married Baker in 2011, even though he had pleaded guilty to felony possession of a controlled substance three years earlier. In February 2009 he was ac­cused of domestic violence after allegedly assaulting a family member. But AshLee’s mother claims the charges are untrue.

“Heather has never been in trouble,” Deborah Frazier told The ENQUIRER.

But the insider said: “Thank goodness Sean didn’t end up with AshLee. They would have spent their married life bailing his in-laws out of jail!”
