“I’ll volunteer to marry them in the jail if they surrender,” Sheriff Ron Kalanquin said Monday. Kalanquin said he wanted the Lapeer couple off the streets before their cash ran out and they attempted another robbery.

A 24-year-old man and a 23-year-old woman are suspected of taking about $5,000 in the Sept. 19 robbery of a Lapeer County Bank & Trust branch in Deerfield Township, about 60 miles north of Detroit.

Detectives determined that the robbery money was used to buy wedding rings, pay back rent and pay the woman’s attorney for work done in a child custody case, The Flint Journal reported.

The couple met after the man was released from the county jail and was introduced to her by another ex-inmate, Kalanquin said.

“We believe they could still be in the area, but could also be somewhere in Michigan or beyond,” Kalanquin said. He appealed to the couple’s relatives and friends to alert police to their whereabouts.
