An updated lawsuit filed against a Michigan high school documents Ethan Crumbley's 'unusual' behavior before he allegedly opened fire.
The suit reveals warning signs leading up to the shooting which included 15-year-old Crumbley bringing a bird's head in a Mason jar filled with yellow liquid three weeks before the massacre took place, according to the Detroit Free Press, which reported its findings after exclusive access to the revised lawsuit.
Crumbley was also revealed to have allegedly brought bullets to class and put them on display and researched ammunition on his phone only a day before the shooting.
In the $100 million lawsuit filed against Oxford High School, officials are being targeted as the responsible party for the November 30 shooting that saw four students killed and seven others injured.
Crumbley allegedly posted on Twitter later on November 29, writing: 'Now I am become Death, the destroyer of worlds. See you tomorrow Oxford,' the Detroit Free Press reported Friday.
The Michigan high school has since been singled out for being made aware of Crumbley's behavior but taking no action as they were said to have allegedly told students and parents there was no reason for concern.
Following the shooting, Crumbley remains in custody and is being charged as an adult for his involvement in the deadly shooting.
His parents James, 45, and Jennifer Crumbley, 43, have also each been charged with involuntary manslaughter on claims that they made the gun accessible for their son prior to the incident.

The suit revealed that Crumbley scribbled violent drawings on his math homework and in his journal as well as exhibiting other behaviors such as bringing a severed bird head to school and putting bullets on display in his classroom the day before the shooting
The updated suit, which was filed by Michigan firm Fieger Law, has added 11 new counts after being made aware that the school knew of Crumbley's behavior.
'The school was on alert about Ethan,' firm attorney Nora Hanna told the Free Press. 'There are a million things that they could have done.'
New details in the suit emerged the extent of Crumbley's behavior leading up to the shooting, which included allegedly drawing a picture of a gun on his math homework and a sketch of someone opening fire at the school in his journal, recording himself torturing animals, messaging his mom about 'ghosts and demons in the house' and even texting his friend 'It's time to shoot up a school JK.'
In addition, video surveillance revealed Crumbley had allegedly put a severed bird's head in a bathroom stall after he kept it under his bed for six months, according to Hanna.
An email was sent out by the school after students allegedly found and reported it.
'Please know that we have reviewed every concern shared with us and investigated all information provided… (we) want our parents and students to know that there has been no threat to our building nor our students,' the email read, according to the Detroit Free Press.

A severed deer's head was also found in the school courtyard only weeks before, on November 4, as well as messages written in red paint found on the pool deck and windows of the property.
Parents also complained to the school that students were receiving threatening messages during this period.
'I know I'm being redundant here, but there is absolutely no threat at the HS [high school]," the principal, Steven Wolf, stated in the email, which was cited in the lawsuit.
'Large assumptions were made from a few social media posts, then the assumptions evolved into exaggerated rumors.'
It remains unclear if Ethan Crumbley was the culprit for these incidents.
However, the school continued to receive criticism for taking little to no action against him as even students were aware of his allegedly 'violent' tendencies.
The suit noted that the school should have gotten Child Protective Services involved, which is required by law. The school allegedly only threatened to do so, which purportedly only gave him more time to plan the shooting.
In addition, the suit claimed that a school liaison officer was barred from a meeting with Crumbley and his parents after a teacher found his gun drawing.
It is alleged that two of the school's counselors chose to keep the drawing away from the officer.
The school also allegedly told students 'to stop spreading information over social media' after they received the threatening messages in early November.

School district attorney Tim Mullins has since defended the district for the way it handled the incident.
Mullins also said he is attempting to dismiss the lawsuit on immunity grounds,
