Lacroix, 25, will reportedly plead guilty to all charges and will serve a four-year prison sentence followed by a tree-year "supervised release."
The Briston Community College student faced similar charges in 2008 when he hacked into Hilton's cell phone. A juvenile at time, Lacroix only served 11 months in a juvenile detention center after being charged with 18 counts of computer hacking crimes. Lacroix has also pleaded guilty to making bomb threats and hacking into a phone company's network to set up free phone lines for his friends.
The 25-year-old man is now facing charges of changing his and two other students grades after hacking the BCC computer network as well as obtaining personas bank records of thousands of people and accessing a law enforcement network with access to intelligence records, arrests warrants and sex ofender information.
The Department of Justice did not specify which police department Lacroix hacked into or how he managed to obtain the victims' bank records.
Prosecutors told the Washington Post in 2005 that Lacriox's actions had cost around $1 million to his victims.
