Investigator report states January 2013 to get a warrant for a dui blood but the report suppose to be dated jan 2014

A warrant must state with specificity and accuracy the date, place, and items to be seized. You have an excellent issue to attack this warrant since the date is wrong.

It is impossible to predict any outcome based on the limited information presented, but this appears to be a matter worth pursuing. Hire the best lawyer you can afford, and follow her/his advice.

I would definitely contact an experienced defense attorney in your area as this will certainly be an issue. Good luck.
