Sources connected to the case tell us ... in deciding whether to prosecute, the D.A.'s Office heavily considered 3 incidents where Lindsay allegedly pilfered expensive items:
-- She was suspected of taking a $400,000 necklace in 2009 from an Elle Magazine photo shoot.
-- She was accused of stealing a $12,000 mink coat in 2008 from a NYC nightclub.
-- She was accused of taking a $35,000 Rolex from a "friend" in 2010.
Lindsay was not prosecuted or convicted in the three cases, but sources say prosecutors not only heavily considered the prior incidents in making their decision ... they will ask the judge to admit the three incidents into evidence to show "prior bad acts" if the case goes to trial.
Our sources say there are two other factors that weighed heavily in the decision to prosecute:
-- Lindsay has had repeated run-ins with the law, including two DUIs.
-- She repeatedly thumbed her nose at the legal system by failing to perform her probation requirements, blowing off court appearances (remember that trip to Cannes?) and acting disrespectfully before the judge (the whole fingernail thing).
As TMZ reported, the D.A. has a surveillance video which shows Lindsay walking out of a Venice, CA jewelry store with the $2,500 necklace in question. The necklace is partially hidden by other trinkets around Lindsay's neck.
Lindsay will be arraigned today at 1:30 PM PT. Lindsay will be in court, accompanied by her lawyer, Shawn Chapman Holley. Prosecutor Danette Meyers reps the people of the State of California.
TMZ will livestream the hearing.
