Six weeks after New Jersey therapist Brooke Hanlon was brutally stabbed to death, the mystery surrounding her killing has grown even more unsettling — and two former FBI experts say several key clues could prove pivotal in solving the case.
James R Fitzgerald and Gregg McCrary, both renowned former FBI agents and criminal profilers, separately examined the case for the Daily Mail and highlighted a range of forensic and behavioral issues investigators are likely weighing, including whether the attacker left DNA behind and how husband Conor Hanlon’s opening words during his 911 call may have helped establish an immediate timeline.
Brooke Haggerty Hanlon, 35, the daughter of a prominent Big Pharma attorney, was discovered stabbed to death on June 6 on the second floor of the Chester Township home she shared with her husband and their infant daughter, Avery.
Their observations come as the Morris County Prosecutor’s Office continues to release few details about the investigation, leaving anxious neighbors uncertain over whether detectives have named a suspect or identified any person of interest.
‘It doesn’t feel reassuring that detectives are still asking questions as if they still don’t know anything. Nothing about this makes any sense,’ one worried neighbor told the Daily Mail.
Concern in the neighborhood grew again this week when residents said they saw Conor Hanlon and his white Volvo return to the Pottersville Road property where Brooke was found dead. Neighbors said the vehicle had not been seen there since the time of the murder.
According to neighbors who spoke to the Daily Mail, the Volvo remained at the home for several hours one afternoon before leaving around 8pm.
Conor Hanlon, 36, originally from the Boston area, began working for a local construction company after the couple moved back two years ago to Brooke’s affluent hometown of Chester Township. Neighbors said that, until this week, they had not seen him in the five weeks following his wife’s death. Authorities have not identified Conor as being connected to the murder.

Last week, the Daily Mail exclusively revealed the 911 call that captured the psychotherapist’s husband pleading for help after discovering his wife’s body
In their interviews with the Daily Mail this week, both former FBI agents stressed that there is not enough information out yet to pinpoint any suspects in the case and cautioned against jumping to conclusions too early.
But one detail that caught the attention of Fitzgerald, a forensic linguist who was pivotal in the arrest of the Unabomber in 1996, was the language used during the six-minute 911 call to police.
‘I just found my wife!… She’s not breathing or conscious,’ Hanlon, 36, shrieked on the call, exclusively revealed by the Daily Mail last week.
‘What the f***, what the f***! I need CPR. Oh my God there’s a laceration in there!’
He can also be heard telling the 911 dispatcher that he needs CPR and an ambulance for his wife while saying there is ‘blood everywhere.’
‘The interesting thing I found about this is both of the first two sentences stated by Conor Hanlon were exculpatory in terms of his activities at the scene that day,’ Fitzgerald, who co-hosts the Cold Red podcast, told the Daily Mail.
Hanlon’s opening words to the 911 dispatcher, ‘I just found my wife,’ immediately caught his attention, he said.
‘So he’s putting a timestamp’ on when he says he first encountered her, Fitzgerald explained.

Hanlon’s next statement, ‘I don’t know what’s going on,’ followed immediately afterward.
To Fitzgerald, those opening seconds are precisely the sort of language investigators would spend hours dissecting during formal interviews.
‘”I just found my wife” would mean to detectives well let’s go over your time schedule for the whole day,’ Fitzgerald said. ‘Let’s go over where you were.’
Fitzgerald also noticed that the same phrase appeared at both ends of the 911 call.
When the EMTs arrived, Hanlon can be heard telling them again that ‘I found my wife.’
‘Now he bookends his communications with law enforcement,’ Fitzgerald said.
‘The very beginning, “I just found my wife,” and then the very end… “I found my wife.” “Found” being an operative word.’
Fitzgerald said Hanlon’s description of his wife’s injuries also stood out.
Rather than saying his wife had been stabbed or was bleeding, Hanlon told the dispatcher there was ‘a laceration in her chest.’
‘Laceration is different than puncture… different than slash,’ Fitzgerald noted.
He explained that detectives would be conducting a thorough victimology – the process of understanding why a particular person became the victim.
‘The police have to rule out the husband before they move on to anyone else,’ Fitzgerald said.
McCrary, one of the FBI’s best-known former investigators, focused on the physical evidence detectives would be analyzing.
For him, every homicide investigation begins the same way.
‘The statistical probability is always that there’s a known relationship between the victim and the offender in the vast majority of violent crime cases,’ he said.
‘Somebody wants somebody dead for a personal reason, a business reason… there’s some motive behind that rather than just a random stranger-based sort of case.’

Rather than immediately searching for an unknown killer, McCrary said experienced detectives begin with the victim herself, working outward in what he described as ‘concentric circles.’

‘You look at the people closest to the victim first, the nature of those relationships,’ he said. ‘The least likely scenario… is that it was a stranger.’
The process, he said, includes examining the marriage, finances, insurance policies, recent relationships, possible affairs and any other motive before broadening the investigation.
Chester Township sources have questioned whether Brooke Hanlon might have been attacked by a patient or a former patient.
She apparently worked mostly out of her home for LifeStance Health in nearby Bernardsville and focused on teens, children and young adults in her practice.
The crime scene itself, McCrary said, should answer many of the investigators’ biggest questions.
If Brooke Hanlon suffered multiple stab wounds, detectives would immediately want to know whether she had defensive wounds on her hands and forearms, indicating she fought back.
‘The more stab wounds we have, the more likely the offender has cut himself at the scene,’ McCrary said.
That possibility makes DNA one of the most important pieces of evidence.
Retired FBI agents James R. Fitzgerald and Gregg McCrary reviewed the case for the Daily Mail and highlighted key clues and behavioral evidence that investigators would be examining closely
Investigators would be looking for blood from more than one person, particularly if the killer accidentally cut himself while stabbing the victim.
If someone genuinely performed CPR on a stabbing victim, McCrary said, investigators would expect that person’s hands and clothing to be covered with the victim’s blood.
But detectives would also be studying whether the blood was merely transferred during lifesaving efforts or whether it appeared as cast-off or impact spatter consistent with someone wielding the knife.
Investigators, he said, would also be searching for evidence that someone tried to clean up afterward.
‘They would pull the drains and do an in-depth search for any fresh blood at the scene,’ McCrary said.
Signs of cleanup, he noted, are generally not associated with stranger attacks.
McCrary also questioned whether the publicly reported timeline ultimately withstands forensic scrutiny.
The 911 call came in at 4.29pm that fateful Saturday. If investigators are working from a scenario in which Hanlon briefly left the home before returning to find his wife mortally wounded, detectives would be testing every minute of that account against the physical evidence, McCrary said.
Multiple neighbors told the Daily Mail they all texted Conor immediately after seeing swarms of police cars and officers at the family’s home on the afternoon of June 6 but never heard back
They would compare the estimated time of death with receipts, surveillance video, phone records and electronic data.
They would also be looking for blood on doorknobs, door frames or any route an attacker would have used to leave the residence.
Like McCrary, Fitzgerald said detectives would be trying to nail down why a particular person became the victim.
‘Why was she chosen to be murdered?’ he asked. ‘Is it robbery? Is it theft? Is it a sex crime? Was there a burglary taking place?’
Fitzgerald said the homicide appears more consistent with a deeply personal act than an elaborately planned murder.
‘This looks like a crime of passion of some sort,’ he said.
The couple’s daughter is believed to be staying with Brooke’s parents in Chester.
Chester Township sources have told the Daily Mail that Hanlon reportedly has a strong alibi.
One local resident said Hanlon was seen outside the home on the Saturday morning of the murder but his alibi reportedly involves a trip he took to a nearby store at some point during the day.
