At the beginning of 2020, Breonna Taylor posted on social media that it was going to be her year. She was planning a family with her boyfriend, Kenneth Walker; she had a new job and a new car. She had also blocked Jamarcus Glover, a convicted drug dealer with whom she had been romantically involved on and off since 2016, from her phone.

But forces were already in motion. The Louisville Police Department was preparing raids on locations it had linked to Mr. Glover — and Ms. Taylor’s address was on the target list.

In the raid that ensued, Ms. Taylor was fatally shot. Her name has since become a rallying cry for protesters. Today, in the first of two parts, we explore Ms. Taylor’s life and how law enforcement ended up at her door.

Guests: Rukmini Callimachi, a correspondent for The Times, and Yoruba Richen, a documentary filmmaker, talk to Ms. Taylor’s mother, Tamika Palmer; her boyfriend, Kenneth Walker; and her cousin, Preonia Flakes.
