ALLEGAN (WKZO) -- It doesn’t take much to break a case when you are investigating a crime. A pair of shoes, a finger print, a well timed tip.

In this case, it was a Glock handgun found in a van after a high speed chase in Holland that began to unravel this mystery. Forensics matched the shell to last month’s home invasion and shooting at the home of a medicinal Marijuana grower in Allegan.

James Finch was shot in the leg, beaten, and robbed of his dope. It’s led to the arrest of three other suspects. Jabri Weatherspoon and his Uncle Keith, Dimitri Galaviz and Tavale Robinson. have all been arrested.

Two are being held in Ottawa County where they were busted during that chase. The other two were arrested in Allegan County.

Finch had surveillance cameras installed in his home and they captured video of the robbery, which may aid the prosecution.
