New details have emerged about the contents of the car that Jennair Gerardot was driving the night she killed her husband's mistress and then herself in Pennsylvania, raising the possibility that she had been watching her target before breaking into her home.

Police in Radnor Township also revealed that taking her own life was likely not a part of Gerardot’s original plan. A bag containing a change of clothes and a wig was recovered from the scene, suggesting that the woman had an exit strategy.

Following the shooting deaths of Gerardot, 47, and her romantic rival, 33-year-old Meredith Chapman on Monday, officers recovered binoculars, ear plugs, latex gloves and additional ammunition from the shooter's rented black Cadillac XTS.

Also recovered from the vehicle was a receipt from a local gas station bearing the time stamp 2.40pm, indicating that Gerardot had spent some time in town before breaking into Chapman's new home on Lowrys Lane, lying in wait and shooting the younger woman when she returned home, reported NBC10.

Gerardo's car was later found on a nearby street. She had rented the Cadillac on April 13 in her hometown of Wilmington, Delaware, and used the vehicle to travel to Pennsylvania.

Police said earlier that Gerardot traveled from Delaware to Pennsylvania by train.

Radnor Township Police Lt. Christopher Flanagan also revealed said it would be a ‘reasonable conclusion’ that Gerardot did not intend to kill herself. It is unclear why the woman decided to commit suicide after shooting Chapman in the head.

Philly.com reported Wednesday that a month before the murder-suicide, Gerardot, went on the neighborhood social media app NextDoor asking for recommendations for 'an EXCELLENT marriage counselor for couple on brink of divorce.'

She went on, writing: 'We will need someone who is very educated and experienced dealing with couples issues including infidelity, depression, traumatic experiences, child/parent dynamics, being accountable for actions, etc.'

It remains unknown whether Jennair and Mark Gerardot ever went into counseling. What is certain, according to police in Radnor Township, Pennsylvania, is that on Monday, the scorned wife broke into Chapman's home and shot her when the woman as soon as the woman opened the door. She then turned the gun on herself.

Trouble in paradise? A month before Jennair Gerardot, pictured above with husband Mark, killed his mistress and then herself, she had tried to seek help to save her unraveling marriage

Crowd-sourcing: On at least two occasions within the last two months, Jennair had gone on the social media app NextDoor asking for marriage advice

Jennair's March plea seeking help with her unraveling marriage was not her first foray into crowd-sourcing relationship advice.

In February, the woman went on the app, writing that she and her husband had just moved to Delaware for his new job at the University of Delaware, and that not long after Mark asked for divorce.

'I don’t know anyone and am completely clueless to the area,' Jennair wrote. 'Can someone please recommend a reputable and successful and driven divorce attorney?'

Meredith, the newly hired assistant vice president of Villanova University, was having an extramarital affair with 49-year-old Mark Gerardot, according to police.

His wife Jennair somehow found about her husband’s infidelity and set into motion a deadly plan of revenge targeting her younger romantic rival – a plan that she detailed in a series of text messages and emails.

‘Detectives are still sorting that out,’ Police Superintendent William Colarulo said of Jennair’s incriminating writings.

On Monday, Jennair grabbed a Taurus Tracker .357 revolver, got into her rental car and headed to Pennsylvania, where she knew Meredith had relocated about a week earlier for her new job at Villanova, reported Philly.com.

There, she broke into the three-store brick house and proceeded to wait for her nemesis to come home.

The 33-year-old woman was married to former Newark, Delaware, City Councilman Luke Chapman for nearly a decade, but Colarulo revealed on Tuesday that the couple had separated.

Meredith, a 2007 graduate of the University of Delaware, worked for the school in media relations and marketing and ran unsuccessfully for a state Senate seat in Delaware in 2016.

Mark Gerardot joined the staff at the University of Delaware as creative director earlier this year and briefly worked under Meredith’s supervision.

Less than two hours before her death, Meredith gushed on her Instagram account about her new position at Villanova, writing that she ‘couldn’t be more excited.’

‘Just a week on the job and I’m already feeling the love from #NovaNation! #GoingNova #HigherEdMarketing#NewAdventures’ she posted at 5.42pm.

Later that evening, Meredith arrived at her new home on Lowrys Lane in Radnor Township, parked her Audi in the driveway, opened the door and walked straight into Jennair Gerardot’s ambush.

Mark and Meredith were supposed to meet up for dinner on Monday night, but the woman never made it to the restaurant.

While he was waiting for his girlfriend to arrive, Mark began receiving disturbing text messages from his wife, which led him to Meredith's home, according to police.

Officers who responded to Meredith's home were met by Mark, who warned them that his wife might be inside the residence.

When police responded to the scene, they found the bodies of both women on the first floor of the residence, which was splattered with blood. The suspected murder weapon was found under Jennair's body in the kitchen.

Radnor Township Police Superintendent Colarulo shared additional details concerning the deadly plot, including how the jealous wife cleaned up the shattered glass from the window she used as her entry point so that her victim would not be tipped off that someone had broken in.

Meredith, nee Sullivan, married Luke Chapman in 2009 and the couple lived in Fairfield Crest, Delaware, with their dog Indy. As recently as March 30, she posted a message on her Facebook page referencing her husband's political career.

Earlier this year, Meredith's husband announced he would not be seeking re-election for a fourth term on the Newark City Council.

In 2016, Meredith ran an unsuccessful campaign to unseat incumbent State Senator Dave Sokota in Delaware’s District 8.

Meredith had served as the director of digital communications and an adjunct professor at her alma mater, University of Delaware, until earlier this month

She ended up losing the election to the veteran Democrat from Newark by 5 percentage points.

Before trying her hand at politics, Meredith worked as a reporter for the Philadelphia-based PBS affiliate WHYY-TV and was later hired as a communication manager for then-Congressman Mike Caste, a Republican.

Upon learning the news of Meredith’s passing, Castle described his former aide as industrious and capable.

‘I’m terribly saddened. She was a very good person and one of the last people I would have thought could have something like this happen,’ he said. ‘It’s a terrible shame.’

Meredith, a native of Pennsylvania, graduated from the University of Delaware with a Bachelor's degree in communication and a Master’s degree in education.

Villanova University spokesman Jonathan Gust said the school was informed Monday night about her death.

'Our hearts are broken by the devastating loss of our new colleague,' he said. 'The thoughts and prayers of the entire university community are with her family, friends and colleagues during this extremely difficult time.'
