1-year old Brooklyn boy and child's father shot by police officer mother in double murder/suicide

A police officer with 13-years of experience on the Brooklyn police force inexplicably shot to death her boyfriend, then her 1-year old son and son of the boyfriend, then turned the gun on herself, in their Brooklyn, New York apartment.

A 19-year old son escaped alive.

From an article:

When authorities entered the first-floor apartment, they found the officer's 33-year-old boyfriend dead in the doorway. The bodies of the 43-year-old officer, a 13-year cop with the 108th precinct, and the child were found in the bedroom. 

All three victims died of gunshot wounds, authorities said 

The officer's teenage son told police he spoke with his mother when he first woke up Monday morning and everything seemed fine. Then, around 8 a.m., he told police he heard a gunshot -- then more gunshots -- and he saw his mother standing in the apartment with a gun in her hand. 

The teenager told police he asked his mother what was happening and she apologized, according to law enforcement sources. Then the officer went into her bedroom and placed the baby on the bed. The 19-year-old son heard another gunshot and jumped out the window to find police.
