A 56-year-old woman accused of “keying” as many as 175 new vehicles at 10 metro Detroit dealerships, kept a diary of those exploits and others, including the stalking and threatening of a neighbor, say police.

Marian Bryant of upscale West Bloomfield Township, MI, is in jail on bonds totaling $700,000.

The car paint scratchings caused $100,000 in damages to dealership inventories.

“She seems to have a problem with car dealerships,” says a West Bloomfield police officer.

Charges include malicious destruction of property and aggravated stalking.

“We're not sure about her mental stability,” the officer says.
