BALTIMORE — Police link an armed standoff in Baltimore County to a murder in Baltimore City's Brewers Hill neighborhood.
Overnight Monday Baltimore City Police visited the Porter apartment complex on Toone Street, looking to speak with 28-year-old Amy Armstrong.
Meanwhile, in the backyard of a home in Owings Mills, County officers were negotiating with her 27-year-old boyfriend, Gabriel Gomez-Fiorenza, who was carrying an AR-15 threatening to take his own life.
Police initially planned to ask Amy why Gabriel was upset, but she never answered the door.
After peacefully surrendering Gabriel confessed to shooting Amy inside their apartment.
Word got out to Baltimore City officers who entered Amy and Gabriel's apartment, to find her shot to death in the kitchen.

Police discovered a .223 caliber cartridge on the floor, indicating Amy was killed with Gabriel's AR-15.
During an interview with detectives Gabriel said he and Amy had an argument earlier in the day. It's unclear what about.
He claims to have grabbed his AR-15 with plans to end his own life.
Amy reportedly heard Gabriel racking his rifle, prompting her to try and wrestle the gun away.
As Amy struggled to pry the weapon away, Gabriel recalled his finger remaining on the trigger, causing it to fire and strike Amy in the head and facial region.
Gabriel remembered calling Amy's name after she collapsed on the kitchen floor, but did nothing to help, not even a call to 911.
Instead he got in his car and drove to his family's home in Owings Mills, where he engaged in a standoff with police.
Gabriel now faces first and second degree murder charges.
Together, Gabriel and Amy operated a local bartending business called Mr. Mixology.
A GoFundMe has been launched to help support Amy's family.
