I'm a house cleaner. we had a regular clients 2 story condo broken into while we were upstairs. i heard a noise downstairs. checked things out. the master bedroom was ransacked. a gun was taken along w/2 clips. now the wife and i are suspect. we've been cleaning for these people in this community for 6yrs. incident free! highly recommended services. we,ve been questioned by D.T. and asked to take a CVSA. Do i need to lawyer up? how accurate r these tests?
