(CNN)A Kentucky woman working as an EMT was killed after officers forced their way inside her home and exchanged shots with her boyfriend, according to a lawsuit filed by her mother.
A Kentucky EMT was shot and killed during a police raid of her home. The family is suing for wrongful death
The officers were executing a search warrant in a narcotics investigation, the Louisville Metro Police Department has said, when they entered Breonna Taylor's apartment just before 1 a.m. on March 13.
Taylor's mother, in a wrongful death lawsuit filed last month against the three police officers involved, argues that the officers should have called off their search of Taylor's apartment because a suspect police were looking for had already been arrested by other officers executing a warrant at a separate location.
Attorney Benjamin Crump joined the family's legal team this week, vowing to seek justice for Taylor, who was shot at least eight times, according to the lawsuit.
"Despite the tragic circumstances surrounding her death, the Department has not provided any answers regarding the facts and circumstances of how this tragedy occurred, nor have they taken responsibility for her senseless killing," Crump said in a statement.
According to a police affidavit for a search warrant for the raid obtained by CNN affiliate WAVE and reviewed by CNN, police said another man, as part of a trafficking ring, was shipping drugs to Taylor's apartment to avoid detection and was using the apartment as his home address.
According to the police affidavit, the detective believed the suspect "may be keeping narcotics and/or proceeds from the sale of narcotics" at the apartment "for safe keeping."
The search warrant authorized the police to search Taylor's apartment, two vehicles, and three persons, including Taylor, and to seize, among other things, drugs and drug paraphernalia, money, safes, weapons, documents, and computers.
At the time of the raid, officers knocked several times and announced they were police with a search warrant, Lt. Ted Eidem, of the police department's Public Integrity Unit, said in a news conference March 13.
He said the officers forced entry into the apartment and were met immediately with gunfire, to which they returned fire.
The family's lawsuit, filed April 27, alleges the police did not announce themselves or knock at all.
"The defendants then proceeded to spray gunfire into the residence with a total disregard for the value of human life," the lawsuit says.
Taylor's boyfriend, Kenneth Walker, was also at the apartment and called 911 when the police burst in, the lawsuit says. He was licensed to carry, the suit says. Police say he fired at the officers.
The family's lawsuit claims "any defensive force used against the Defendants was due to their forcible and unlawful entry into Breonna's home."
A police sergeant was shot and wounded, according to police.
There is no body camera footage of the incident, police said in the March 13 news conference.
CNN reached out to the department for comment, but a spokesperson declined to comment, citing the ongoing investigation.
The Public Integrity Unit is conducting an investigation, the police department said, and the officers have been placed on administrative assignment while it continues.
Walker was arrested and charged with attempted murder of a police officer and first degree assault, according to online court records.
He was released for home incarceration, and his next court date is scheduled for June 25, according to court records.
CNN has emailed and called Walker's lawyer and is waiting to hear back.
