MINNEAPOLIS — The mass shooting that killed two and injured several others this week at Shoreline Plaza in downtown Minneapolis has been a tragic step backward for a neighborhood trying to improve safety.

Minnesota officials named Carlton Neal Johnson II as the suspect in a Sept. 2 shooting that left two people dead. Here's what we know about him.

The gunman, who fatally shot two people and wounded several others at an apartment building where he lived, was facing eviction.

The volatile behavior of a man suspected of carrying out a mass shooting in downtown Minneapolis on Wednesday had been well-documented by officials in various county and city agencies. It did not stop him from having the ability to possess the firearm that was used to allegedly carry out a shocking act of violence.

He had threatened his neighbors, repeatedly showed off his pistol, and warned he was planning to shoot people, according to building residents, court documents and law enforcement officials.
