Police said they were told Jackson willingly got into a vehicle with an acquaintance before she disappeared.
Graham was found hiding in his attic around 11:30 p.m. on Friday.
Police said he has a history of violence and is considered extremely dangerous.
A cause of death has not yet been released.
The courtroom at Hartford Superior Court was packed as Graham faced a judge on Monday morning.
At first, the state recommended Graham’s bond be set a $3 million. At that point, an unidentified man got emotional and walked out of the courtroom.
The state told a judge that Graham had a previous murder/rape conviction, however his attorney said that claim was not accurate.
In court, Graham’s attorney Deron Freeman argued that there was very little evidence to suggest he had anything to do with Jackson’s disappearance.
Freeman added that Graham and Jackson had been in a relationship for four years and were a little more than friends.
He disputed the fact that blood was found in Graham’s car and added that his client had been an “open book” with police during their investigation.
After Freeman's requested a bond of $10,000, the judge set it at $2 million because of the tampering with evidence charge. At that time, two people called out “no” and one unidentified woman walked out of court.
Police said their investigation into Jackson’s death continues. They continue to ask that anyone with information call Bloomfield police at 860-242-5501.
