NEW YORK (NYTIMES) - Buried in a sea of disturbing videos that Frank R. James posted on YouTube in recent weeks was a plan.
In between bigoted screeds tied to current events, he described an itinerary that would take him on a trip from Milwaukee in late March to the East Coast, where he was born.
In more than one video, he recorded himself behind the wheel of a rented van, apparently making that journey back to what he called "the danger zone".
And the day before the attack in which police say he opened fire on a New York subway car, shooting 10 people and injuring at least 13 more, James posted a video in which he said he had often wanted to kill and to "watch people die" right in front of him.
The thought of prison restrained him, he said, adding: "It's important to think about what you're going to do before you do it."
James was arrested on Wednesday (April 13) and charged with committing the worst crime on New York's subway system in nearly 40 years.
Investigators and the broader public are still struggling to piece together what made him tick - and how the hours of footage he posted offered a hidden preview of an attack he may have been planning for weeks.
In a sense, James's travel eastwards retraced the steps he had taken earlier in life. He was raised in the Bronx borough of New York but mostly lost touch with his family as he grew older, his sister said.
He drifted south and then west, to Newark, New Jersey, then Philadelphia, then Chicago - arrested many times but never convicted of anything serious enough to prevent him from buying a gun, which he did in Columbus, Ohio, in 2011.
He landed in Milwaukee, where neighbours in his most recent home described him as a sullen, irascible loner. But there, apparently alone in his apartment, he built himself a YouTube personality.
Referring to himself as the "prophet of doom", he posted thoughts on race and global affairs and, eventually, threats of violence that, in at least one video, he imagined taking place in New York's subway system.
"He can't stop no crime in no subways," James said of New York City Mayor Eric Adams in one video. "He may slow it down but he ain't stopping it."
He added: "That means you'd have to have police in every station, and that's just not possible."
James was born in 1959 - in New York's Manhattan borough, according to public records, but in the Bronx, according to his sister Catherine James Robinson. Their mother died when James was five, and his relationship with other family members frayed as he grew older, Ms Robinson said.
"He's been on his own all his life, and I haven't had that much contact with him," she said. "He moves from city to city."
One of the last of those cities was Milwaukee, where it was unclear what James did for work. He described himself as a driver, including for the delivery app Instacart. (Instacart did not reply to several requests for comment.)
He seems to have been more focused on his YouTube account, where the videos he posted frequently devolved into outbursts of homophobia, misogyny and offensive comments about black people, Hispanic people and white people.
James, who is black, directed much of his hatred towards black people, whom he often blamed for the way they were treated in the United States.
He expressed admiration for black trailblazers like Martin Luther King Jr. and President Barack Obama but unleashed vitriol on other black people, including Daunte Wright, who was killed by a police officer in Minnesota last year, and other young black men shot by police.
He blamed them for their own deaths, saying, "You play stupid games, you win a stupid prize", and adding that they deserved to be shot.
Current and former neighbours in Wisconsin described him as gruff, standoffish and prone to losing his temper. Ms Keilah Miller, who lived in an adjacent unit to James in Milwaukee, said he had blown up at her after she had left her key in her lock, yelling, "Don't ever do that again!" She said he had few visitors.
In a video posted on March 18, James said he picked up a Penske van and was planning to leave Milwaukee the following day. Two days later, shooting a video from the road, he said that he had packed up his apartment, emptied his storage unit and set out early on a trip to Philadelphia, where he was planning to move.
Filming himself from the rented van, he said he was struggling with his emotions.
"On the drive, I'm just thinking because I'm heading back into the danger zone, so to speak, and it's triggering a lot of negative thoughts, of course, because I do suffer from - have a bad case of post-traumatic stress from all the things I've been through," he said in the video.
Once in Philadelphia, James said he was driving to a storage locker facility to store his belongings. He then gave a brief video tour of a hotel room in New Jersey. "All my troubles started in the state of stinking New Jersey," he said, using an expletive.
There was truth to that aside: Police officials said that James was arrested three times in New Jersey, the first time in 1991, the most recent in 2007. He was arrested nine times in New York from 1992 to 1998 and was charged with possession of burglary tools, criminal sex act and criminal tampering.
James faced two charges for making terroristic threats in New Jersey in the mid-1990s. But he was found guilty of harassment, a lesser charge, and sentenced to probation and counselling.
In his videos, James ranted against counselling programmes that he said were supposed to make him feel better but wound up making him worse off.
He directed much of his ire towards workers at the South Bronx Mental Health Council in New York, although it remains unclear when he began counselling or why. Court documents suggest he was already enrolled in a different programme in 1997 in New Jersey at the time he was convicted.
In Philadelphia, by his own account, James was having some housing trouble. In a video posted on March 27, he said that a heater had broken where he was staying and that he had to move to another room.
The following day, he began his stay at a property owned by Ms Janet McDaniel, 74, a former case worker for the Pennsylvania Department of Public Welfare who manages several short-term rental properties. James booked the stay through Evolve, a short-term rental platform.
Ms McDaniel said that James had originally been scheduled to leave the duplex - near the corner of a block in Philadelphia's Nicetown neighbourhood, not far from Temple University Hospital and the medical school campus - on Sunday but appeared to have extended his stay until this Friday.
She had little contact with him - he called her once to tell her that the cable was not working - and entered the apartment on Tuesday, expecting him to have left, and was surprised to find a number of belongings still there, including a nearly empty suitcase and a pair of scissors. Food had been left in the refrigerator, clothes were hanging in the closet and the television was blaring.
"At that time, I decided let me get out of here," Ms McDaniel said.
The same morning, federal agents swooped into the property. In searches of multiple properties associated with James in Pennsylvania, law enforcement officers were able to find ammunition for a 9mm gun as well as a barrel that would allow for the use of a silencer, and ammunition that can be used in an AR-15 rifle.
As a short-term tenant, neighbours said, James had kept to himself, so much so that he seemed more like a construction or maintenance worker than a tenant.
Ms Ayana McKay noticed James during his two weeks at the property but rarely interacted with him, she said. Ms McKay, 23, was home when federal agents barged in on Tuesday morning, pointing guns at her and demanding to know whether she was a hostage or was hiding anyone in her apartment.
At that point, James was in New York, perhaps hewing to a different travel plan. Although in one video he mentioned that he planned to leave the rental this Friday, he said in another that he would stay for only about 15 days, exactly the amount of time that passed between his booking of the rental and the day of the shooting.
