A California woman and three accomplices have been arrested after she allegedly hired a hitman to kill her ex-boyfriend.

Ignacia Cadaos Perkins, 40, of Murrieta, has been charged with murder in connection with the death of 30-year-old Aaron Parr. He was found dead on January 13 inside an apartment in the city, the Murrieta Police Department said.

Authorities responded to the apartment and determined that the circumstances surrounding Parr’s death were suspicious, prompting a homicide investigation.

On January 29, Perkins and an acquaintance, James Lawrence Petri, 43, were both arrested in Alabama. The pair were charged with murder and conspiracy to commit murder, police said.

Investigators have not shared further details on Parr’s death but have suggested that the killing may have been motivated by financial gain, according to the Los Angeles Times.

“Since the initial arrests, Murrieta Police Detectives have continued to diligently examine a substantial volume of physical evidence, digitial evidence, and investigative leads,” police wrote in a Facebook update on their investigation Friday.

“Through persistent investigative efforts and coordination with partner agencies across the United States, detectives were able to identify and locate two additional accomplices involved in this homicide,” the police added.

Last Wednesday, authorities arrested Jerry Wheeler, 34, in Brookhaven, Georgia, and Kenneth Maxwell, 39, in Midfield, Alabama, police said.

Wheeler and Maxwell both face charges for murder, murder for financial or other consideration, and criminal conspiracy to commit murder, police said.

Both Wheeler and Maxwell are awaiting extradition to California, where they will face trial.

Authorities have shared few other details about the circumstances of the killing, citing an ongoing investigation.
