FREEHOLD -- A suspended Neptune police sergeant will be sentenced on Thursday for the June 2015 daytime slaying of his ex-wife on an Asbury Park street.

Prosecutors are expected to recommend a sentence of 30 years in state prison when Philip Seidle, 52, appears before Superior Court Judge Joseph Oxley. Seidle admitted to fatally shooting Tamara Wilson-Seidle in front of their then 7-year-old daughter when he pleaded guilty to aggravated manslaughter and child endangerment in March.

The plea deal allowed Philip Seidle to avoid spending the rest of his life in prison.

The Seidle's oldest daughter, Kirsten Seidle, said in March that the family agreed to the plea agreement.

"To avoid further trauma to our family we have thoughtfully accepted this guilty plea," she told reporters outside the Monmouth County courthouse.

Still looming, however, is a $10 million wrongful death lawsuit against Asbury Park and Neptune Township, their respective police departments, the prosecutor's office and Philip Seidle.

Shelley Stangler, a Springfield attorney representing the estate of Tamara Wilson-Seidle, has told NJ Advance Media she is awaiting the completion of Philip Seidle's criminal case to conduct her investigation into the incident.

The Monmouth County Prosecutor's Office released the findings of its exhaustive internal investigation in June, concluding the responding officers could not have prevented the death of Tamara Wilson-Seidle.

Prosecutor Christopher Gramiccioni, speaking at a press conference, told reporters he recommended the Asbury Park Police Department discipline two of its officers. The investigation found that one officer failed to relay pertinent information to other responding officers and another officer, who was the highest-ranking cop at the scene, twice left to go to police headquarters.

Gramiccioni also called for changes to how law enforcement in Monmouth County shares information relating to domestic violence issues involving police officers.

The couple finalized their divorce, ending a 23-year marriage, just three weeks before the shooting occurred. But police had been called to the couple's Neptune Township home half a dozen times for domestic-related incidents.

Upset after seeing Tamara Wilson-Seidle's boyfriend's car in the driveway of the home they once shared with their nine children, Philip Seidle chased Wilson-Seidle through the streets of Asbury Park before ramming her Volkswagen Jetta on Sewall Avenue on June 16, 2015.

He then hopped out of his vehicle and used his service weapon to fire eight rounds into her through the driver's side window while the couple's daughter sat in her father's Honda Pilot. Seconds later, authorities said, Philip Seidle fired off another four rounds into the vehicle.

During a roughly 45-minute standoff, Philip Seidle held a gun to his head as the public looked on. He surrendered after authorities slid him a cell phone picture of his children.
