72-year-old Robert Lewis Hollie, the suspect who shot and killed Mobile police officer Justin Billa during a homicide investigation last night, filed a protection from abuse order against his ex-wife Fonda Poellnitz in 2015, according to state court records.

The couple, who were married in 2013 but separated less than two years later, found themselves in court after Poellnitz (pictured above) allegedly threw a can at Hollie and “threatened to shoot [him] and drag [him] out of the house,” according to a complaint. Poellnitz was 55-years-old at the time.

According to early reports, Mobile police were responding to the scene of a homicide Tuesday night, where Poellnitz’s body was found dumped on the side of the Ridge Road. The investigation led officers back to Hollie’s house on Avondale Court in the Toulminville community, where Billa was shot and killed and Hollie was later found dead from a gunshot wound. The Mobile Police Department has not yet disclosed whether Hollie was killed by officers or by a self-inflicted gunshot wound.

The couple obtained a certificate of divorce in July 2015, but court records also indicate their relationship was contentious even before the marriage. In March 2012, Poellnitz sued Hollie for fraudulently obtaining the title to a car she bought.

According to the complaint, Poellnitz alleged her driver’s license was suspended at the time, and she mistakingly believed she could not own a car without a valid drivers license. Allegedly, Hollie offered to put his name on a car she bought for $9,000, and transfer the title to her after her driving privledges were restored.

Poellnitz agreed, but once she regained her driver’s license, Hollie refused to transfer the title back to her. By August, Poellnitz filed a motion to dismiss to case, which was awarded by Judge John Lockett.

In Mobile County, court records for Hollie were scant. Aside from the cases involving Poellnitz and a workman’s compensation claim he filed in 2007, there was only one other other — an account collection action filed by Capital One Bank last year for the amount of $1,853.08.

Meanwhile, Poellnitz was the defendant in several civil cases brought by creditors in Mobile and Escambia counties. According to Mobile Metro Jail records, she was also booked three times on charges of domestic violence, in 2000, 2002 and 2015.

The Mobile Police Department has scheduled a news conference at noon today to provide updates on the case. Billa joined the department in January 2016, he leaves behind a wife and toddler son.
