Three people have been charged with murder in connection with fatal shot of a detective during a home invasion in her New Jersey home, officials said.

Detective Sgt. Monica Mosley, of the Cumberland County Prosecutor’s Office in New Jersey, was shot and killed in her Bridgeton home on October 15, according to police.

The Cape May District Attorney’s Office announced Monday that charges have been filed in Mosley’s murder.

Three people — Nyshawn Mutcherson, 29; Jarred Brown, 31; and Richard Hawkins Willis, 32 — were charged with first-degree murder and murder during the commission of a burglary, the prosecutor’s office said. They were also charged with burglary, unlawful possession of a weapon, hindering apprehension and obstruction of justice, among other charges, the office said.

A fourth person — Cyndia Pimentel, 38 — was also charged with hindering an investigation, obstruction of justice and tampering with evidence in connection with Mosley’s death, the office said.

The four defendants remain in custody. Attorney information was not immediately available.

“This is a significant step toward justice for Detective Sergeant Monica Mosley and her family,” Cape May District Attorney Jeffrey Sutherland said in a statement. “We are resolute in our commitment to ensure that those responsible for this horrific act are brought to justice. Our hearts go out to the loved ones and colleagues of Detective Sergeant Monica Mosley at this incredibly difficult time.”

The investigation remains ongoing, the Cape May County District Attorney’s Office said.

Police responded to Mosley’s home around 10:30 p.m. on Oct. 15 for a report of “multiple subjects kicking in the front door of a residence,” the Bridgeton Police Department said in a statement of the press.

Mutcherson, Brown and Willis are accused of breaking into the Bridgeton home and shooting Mosley, according to their arrest affidavit.

Mosley shot one of the suspects, Mutcherson, in the chest before succumbing to his injuries, according to the affidavit.

The three suspects allegedly fled the residence and Mutcherson was treated for a gunshot wound at a Bridgeton hospital, the affidavit states. Police previously said they had detained a person who was treated for a gunshot wound for questioning in connection with the incident. Mutcherson allegedly told detectives he was shot in Millville, New Jersey, according to the affidavit.

In the days following the shooting, Brown, Willis and Pimentel allegedly attempted to “give up, destroy and conceal evidence of the home invasion,” the affidavit states.

Mosley, 51, had three children and four grandchildren, according to her obituary.

She began her career with the Cumberland County Prosecutor’s Office located in Bridgeton in 2006 as a Paralegal Specialist. He became a county detective in 2009.

“The law enforcement community and the state of New Jersey have lost a steadfast and dedicated public servant, but we know that the loss of Sergeant Monica Mosley is felt most deeply by her family, loved ones and colleagues,” New Jersey Attorney General Matthew said Platkin in a statement Monday. “Although nothing will ever bring Sgt. Mosley back to those who loved her, we hope that the focused and coordinated efforts in this case will give them the comfort of knowing that justice is being done.”
