FREEHOLD - The findings of a yearlong investigation into the June 2015 public slaying of Tamara Wilson-Seidle by her ex-husband, Neptune Township police Sgt. Philip Seidle, were released by acting Monmouth County Prosecutor Christopher Gramiccioni on Thursday.

The report of the investigation involved hundreds of witnesses, thousands of pages of documents, photos and video footage from witnesses and police cruiser dashboard cameras.

Because the gruesome incident played out in front of dozens of witnesses on an Asbury Park street, there was a lot that the public already knew about how the fatal shooting transpired.

But here are seven things we learned more about from the report:

The history of domestic incidents and suspensions

Philip Seidle was reportedly angered about Tamara Wilson-Seidle's interference with his visitation with their nine children when he chased her through the streets of Asbury Park on June 16, 2015.

Divorce filings and records previously obtained by NJ Advance Media revealed the rocky history of the couple's tumultuous 23-year marriage, as police responded to the Seidle's home 21 times over a 21-year period.

Phillip Seidle, 51, a 22-year veteran with the Neptune Township Police Department, was charged with murder in the shooting death of his ex-wife Tamara Seidle on Sewall Avenue in Asbury Park on June 16, 2015.

Philip Seidle, now 52, received a two-day suspension following an incident on Feb. 2, 2012, that led to an internal-affairs investigation by the Neptune Police Department. Tamara Wilson-Seidle had called police to report her then-husband was verbally harassing her on the phone and that when she got home, Philip Seidle was at the house and approached her in a "menacing manner," Gramiccioni said.

Tamara Wilson-Seidle declined to file charges. However, Neptune police admitted Philip Seidle for a "fitness of duty" examination, not because of his behavior toward Tamara Wilson-Seidle, but rather because he was shouting at the responding officers, Gramiccioni said.

On Feb. 12, 2012, Seidle was found not fit for duty and his service weapon was taken from him. Gramiccioni said Seidle attended therapy regularly until he was re-examined on April 16, 2012.

The prosecutor's officers contacted Tamara Seidle and asked her if she had any concerns with Philip Seidle's service weapon being returned. Gramiccioni said she "expressed no such reservations or fears."

After having only conditional use of his service weapon upon returning to duty, Seidle was eventually fully rearmed by the prosecutor's office.

A second internal affairs investigation was launched "in an abundance of caution" after an incident on March 28, 2014, in which Seidle cursed at responding officers, Gramiccioni said. This time, Tamara Wilson-Seidle had indicated she wanted to file a criminal complaint against him, but she never did. Seidle was placed on administrative leave pending another fitness for duty evaluation, after which he received a 30-day suspension and had to undergo therapy for lashing out at the officers.

The only report of physical confrontation involving Philip Seidle came on Jan. 27, 2012, but it did not involve Tamara Wilson-Seidle. On that day, Philip Seidle's then-girlfriend called Tinton Falls police to report that he had had put his hands around her neck and pushed her following an argument.

Again, no charges were filed and Tinton Falls police never notified the Neptune Township Police Department of this incident, as there was no policy requiring such notification.

The first shots killed Tamara

Philip Seidle first pumped eight rounds into his ex-wife through the driver's side window of her Volkswagen Jetta, then headed to the front of the car where he fired off another four rounds through the windshield, striking her, authorities said prior to the prosecutor's office report being released.

After firing the shots into the car, Seidle then immediately held his service weapon to his head immediately and kept it there for the duration of the approximately 45-minute standoff that ensued.

For more than a year, people following the Seidle case wondered if police at the scene could have saved Tamara Wilson-Seidle's life if they had shot her ex-husband before he fired the second round of gunshots at her.

However, Gramiccioni said that a medical examiner's report concluded Tamara Wilson-Seidle died from one of the shots fired in the first round.

The 911 calls

The report also focused on two 911 calls made during the incident and how they were handled by dispatch.

The first one was made by one of the couple's daughters, who had received a call from Tamara Wilson-Seidle saying their father had threatened to kill her. But the location provided by the daughter was not accurate and indicated Tamara Seidle was in the "area of Mt. Carmel Church," Gramiccioni said. The church is located about a quarter-mile away from where the incident occurred.

However, even an accurate location for Tamara Wilson-Seidle wouldn't have helped: The dispatcher was still on the phone with the daughter as the first round of shots were fired, Gramiccioni said.

The second 911 call came after the first round of shots, and was from Tamara Wilson-Seidle's boyfriend. He reported to a police dispatcher that she was being held against her will on Asbury Avenue, a street that runs through Neptune and all of Asbury Park.

After the shots, Tamara's boyfriend called and said she was being held against her will, but he could not pinpoint her location other than Asbury Avenue.

"We concluded there were not mishandlings or delays on the part of the 911 dispatcher system," Gramiccioni said.

"Ineffective communication and a lack of information did contribute to the confusion at the crime scene as these events quickly unfolded," he continued. "But, tragically, none of them would have changed the result that Tami was killed."

The failure to communicate

The first officer to respond to the fatal shooting scene was already at the corner where the incident occurred, tending to an unrelated car crash when it happened.

The prosecutor's office's investigation determined that this officer did not have a reasonable opportunity to stop Seidle from firing either of the two rounds of gunshots into his ex-wife.

However, Gramiccioni said he would recommend discipline against that first officer at the scene for "failing to communicate critical information."

The officer failed to indicate that there was a car chase, a collision and that the driver jumped out and fired eight shots into the other vehicle, Gramiccioni explained.

"That material information would have been helpful to arriving officers," he said, adding the other officers were only responding to a report of shots fired.

The highest ranking officer left the scene - twice

The third officer at the scene was a neighbor to Philip and Tamara Seidle, so he was familiar with both of their cars, Gramiccioni said.

But, Gramiccioni said, that officer did not relay that information to dispatch.

He was also the highest ranking police officer at the scene at the time and left twice: once to take the Seidle's daughter to police headquarters two minutes after the second round of shots were fired and then again to take the first officer at the scene back to headquarters.

Gramiccioni said he would refer discipline for that officer to the Asbury Park Police Department for demonstrating "poor" leadership, failure to take command and control. He cannot impose discipline, though.

Tamara's frantic attempt to escape

Dashboard camera footage from the first officer to arrive at the scene's patrol car captured Tamara Wilson-Seidle's car trying to elude her ex-husband's Honda Pilot.

The officer and two people he was talking to were nearly hit by Tamara Wilson-Seidle's car as it whipped around the corner onto Sewell Avenue, police dash camera shows.

There is the sound of a car crash, followed by the sound of Seidle firing the first round of shots at his ex-wife.

The officer calls in a report of "shots fired," and then appears to take cover behind his vehicle. He then called in that Seidle has a gun pointed to his head, Gramiccioni said.

The officer can be heard calling Seidle by his first name and pleading with him: "Don't do it Phil!"

Additional officers can be seen arriving at the scene seconds before Seidle fired the second round of gunshots into the car.

Due to their distance from Seidle and how quickly the events unfolded and the fact that he was at risk of harming himself, the prosecutor's office's investigation concluded that the use of force was not the correct course of action for the officers to take at that time.

The safety of civilians was also at risk

Gramiccioni said that the number of civilians in the area added to the determination that shooting Seidle would not have been the correct course of action for the responding officers to take as the shooting and subsequent standoff transpired.

The prosecutor's office released a diagram as a part of the investigation report that illustrates the trajectory that the bullets would have traveled if the five officers fired their weapons.

The diagram indicates that at least four residents were potentially in harm's way at the time.

"At the end of the day, none of these five officers were ever in a position to use reasonable lethal force against (Philip) Seidle," Gramiccioni said.
