Albert Rosenfield is a cynical city-slicker forensics specialist in the FBI who appears to have grown insensitive and indifferent to other people and has contempt for the rural lifestyle of Twin Peaks. However, Rosenfield is revealed to be in fact a conflicted man who, although cynical, holds deep moral convictions.
Reappearance of Agent JeffriesEdit
In February 1989, Albert watched as previously missing Special Agent Phillip Jeffries came to the FBI offices in Philadelphia, stating that he was not going to talk about "Judy" and questions who Agent Cooper is. Jeffries then told Albert, Cooper, and Regional Bureau Chief Gordon Cole of a sort of meeting he was at, above a convenience store. This confused Albert, Cooper, and Gordon further. He also went on saying he and other individuals lived inside a dream. Jeffries said he found "them" in Seattle at Judy's and followed them. Gordon then told Albert to go get a mineral water and Jeffries disappeared. Albert then called the front desk, who said Phillip was never there.
A year later, Cooper told Albert that he predicted that Teresa Banks' killer would strike again, and the victim would be a woman, blonde, in high school, sexually active, using drugs, and crying out for help. Albert responded, "Well, damn, Cooper, that really narrows it down. You're talking about half the high school girls in America!"
Murder of Laura PalmerEdit
He arrives in Twin Peaks with his team on February 26, telling the sheriff's station receptionist Lucy Moran to inform Cooper of his arrival. He then met Sheriff Harry S. Truman, with whom he immediately had a tense relationship due to Albert's belief that the small town's sheriff's department was primitive and amateur, and was unimpressed by the findings of the autopsy. He was threatened by Harry but brushed it off as he got to work with his team.
The following day, Albert got into a fight with Doctor Will Hayward, who wished to stop his further testing on Laura's body so it could be buried for the funeral. When the argument became physical, he was restrained by Benjamin Horne, who took Hayward's side. Albert insisted the funeral should have been delayed as he continued his tests. The disagreement became physical once again before Sheriff Truman and Agent Cooper arrived. Albert let out a string of insults to Sheriff Truman, who punched him causing Albert to land on top of Laura's body. Cooper intervened and sent the Sheriff out, then ordered Albert to let the body be released.
He later presented his findings to Cooper and Truman. Laura was a cocaine user, she was bound with two types of twine, and industrial soap particles were found on the back of her neck. He also noted that wounds on her shoulders appeared to be claw marks. Lastly, he presented a partially-digested plastic fragment bearing the letter 'J.'
When Truman excused himself to go to Laura's funeral, Albert kept Cooper behind, asking him to sign a form regarding the physical attack by the sheriff earlier in the day, but Cooper refused.
Five days later, returned to Twin Peaks under Cole's orders after Cooper had been shot. He went to the home of Leo Johnson, where Deputy Andy Brennan ran inside to warn Sheriff Truman, but stepped on a loose board, hitting himself in the head. This revealed a hidden pair of boots and cocaine.
Back at the Sheriff's station, Albert examined Cooper's gunshot wound. Deputy Andy entered and informs Cooper that Leo was imprisoned in Hungry Horse, Montana on February 9, 1988, confirming an alibi for the Teresa Banks murder, therefore eliminating him as a suspect in Laura's murder, if they were indeed killed by the same person.
He later walked through the hospital with Truman and Cooper. When they saw Ed Hurley, Truman pours Albert a coffee to leave Cooper alone with Big Ed for a moment. Albert was amused by Ed's story of shooting his wife's eye out on a honeymoon hunting trip. He then went to book a room at the Great Northern Hotel.
Later, he sat in the conference room, where he and Cooper went over the events that occurred the night Laura died. Andy cried over a picture of Laura, causing Albert to mock him, upsetting him further.
The next morning, Albert had breakfast with Cooper, who told him about Tibet and that Ronette Pulaski -- who had been present at Laura's murder -- had woken from her coma and said they would show her sketches of Leo Johnson and "BOB," a man whom Sarah Palmer had a vision of, though Albert was skeptical about the latter even existing. He delivered the autopsy report on suspect Jacques Renault, having found that he was smothered with a pillow. He also suspected the Packard Sawmill fire to be a result of arson, and to have been done by Leo. Albert then informed Cooper that his renegade former partner Windom Earle had escaped from a mental institution.
The next day, he went to Ronette with Cooper and Truman as the former extracted a small piece of paper with the letter 'B' from underneath her fingernail. Cooper believed it to have been placed by Laura's killer, and Albert noted that Ronette's IV was tainted. Cooper then told Albert and Harry that he was visited by a giant who gave him three clues. Albert scoffed, "any relation to the dwarf?"
Albert later delivered the results on the cocaine found in James Hurley's gas tank as being from the same source as the drugs in Jacques's and Leo's possession. He also said that the letter 'B' under Ronette's finger was cut from a copy of Flesh World. He stated that the sketch of "BOB" had been run through several agencies, with no results and also noted that Cooper was shot with a Walther PPK, "James Bond's gun," and that he found fibers left from the shooter. He insulted Truman yet again, causing the sheriff to take him by the collar. Albert explained his methods to be built on the foundation of love and calmly said, "I love you, Sheriff Truman," before leaving.
After the body of Laura Palmer's cousin, Maddy Ferguson was found, Albert presented a letter 'O' found under her ring finger, determining her killer to be the same person that murdered Teresa Banks and Laura. He also said that fur from a taxidermy white fox was in her hand. Albert then encouraged Cooper to find the killer before he struck again.
Harry confirmed to Albert and Cooper his suspicion that Benjamin Horne was responsible for the deaths of Laura and Maddy. Albert then presented Horne's blood test.
Albert went to the Roadhouse, where Cooper called several men, including Ben Horne, Leland Palmer, and Leo Johnson. He believed the killer to be there and used "magic" to determine the culprit. He asked to have Ben Horne escorted back to the station, with Leland as his attorney.
They took Ben down to interrogation, but the sheriff and Cooper pushed Leland into the room, with the attorney being thrown into a rage, revealed as BOB's host.
They entered the room, where Leland was restrained and read his rights by Sheriff Truman. Through Leland, BOB laughed and howled as he was interrogated, soon confessing to the murders. Satisfied, the lawmen left the room.
Cooper then went over the evidence against Leland and the events that must have occurred the night of Laura's death. After BOB chanted a poem, the sprinkler system went off, and BOB slammed Leland's head into the interrogation room door. They frantically entered to find Leland bleeding on the floor, BOB apparently gone. Leland expressed his guilt and died in Cooper's arms.
Later, with Dale and Harry, Albert discussed the nature of BOB. He came to the conclusion that Bob is the "evil that men do."
Return of Windom EarleEdit
Following Windom Earle's arrival in Twin Peaks, taunting Cooper, Albert returned to the town. He went to the sheriff's station, where he enthusiastically greeted Truman with a hug before presenting a file on Windom Earle, under Cole's orders. He told them that Earle had been sending boxes to various law enforcement agencies, each containing a piece of wardrobe from his late wife Caroline Earle on their wedding day.
Later, he confirmed to Cooper through forensic analysis that Josie Packard was the one who shot him and was the prime suspect in the murder of Jonathan Kumagai, though Cooper hoped for Harry's sake that this was not the case, as the sheriff and Josie were lovers.
He soon matched up the bullets fired at Cooper, and at Jonathan. He showed Cooper and was eager to arrest Josie, but Cooper wanted more evidence to be absolutely sure that she was guilty and then wished to see if she would confess first.
Later, he came to the station to deliver more evidence of Josie's guilt to Cooper. However, Harry overheard them and left. Josie died later in the night of unknown causes.
As of August 2016, Albert was still an active agent of the FBI.
