On Thursday, someone also stole guns out of two homes in Holland. Police said the break-ins happened in the same neighborhood. One handgun was taken from a home in the 900 block of Columbia Avenue, and three handguns were stolen from a home in the 200 block of East 35th Street.
It's unclear if any of the crimes are related.
