WINONA, Minn. – Somebody really did a job on a parked car in the 600 block of Mankato. Avenue. It was spray-painted. Wires under the hood were cut. So too was the under-dash fusebox. Who did all this? The car’s owner, who discovered the damage about 9:30 a.m., told police she suspected retaliation by the ex-boyfriend of a relative after a nasty split. Police contacted the guy. Nope, he said. He’d had been at work all night, and his alibi checked out. Does the woman have ither suspects in mind? None she can think of.
