Four killed, including 14-year-old boy, and at least 18 shot over weekend in Chicago; there were two mass shootings

February's last weekend of the year saw four people shot to death and at least 18 others wounded.

Of the homicide victims, three of them were killed in a mass shooting on Sunday night in a Chatham home on the South Side. One of the slain was a 14-year-old boy. A fourth person was wounded.

The fourth deadly shooting occurred earlier on Sunday when four people were shot in Pottawattomie Park in Rogers Park on the Far North Side. One woman, a 19-year-old, was killed, one other woman and two men were killed.

It was a mild weekend and while spring hasn't graced Chicago for good yet, soon will see the disastrous effects of Illinois' SAFE-T Act, which abolished cash bail statewide. 

The SAFE-T Act went into effect last fall.
