 ST. LOUIS, MO (KTVI) - Police shot and killed a suspect in north St. Louis at around 11:30am Wednesday. They say the suspect, 18-year-old Mansur Ball-Bey pointed a gun at them during a chase. About 200 demonstrators gathered to protest the officer involved shooting. 
 
 Chief Sam Dotson says two young armed male suspects ran out of the back of a home near the intersection of Page and Walton in north St. Louis on Wednesday. Two police officers executing a search warrant chased the suspects running from the home. 
 
 Officers told the suspects to drop their weapons. Police say one of the suspects raised his gun and pointed it at officers. One of the officers then shot at the suspects. The other officer then fired three more shots. The injured man in his 20's continued running until he collapsed. Police say the other suspect got away. 
 
 A stolen gun from Rolla, MO was recovered near the suspect's body. 
 
 Members of Special Operations and the Tactical Unit were in the area to execute a search warrant. They found three more guns and some crack cocaine in the home. The neighborhood has been flagged for more policing after a few high profile crimes in the area. 
 
 High Crime Area 
 
 Chief Dotson also called the area a hotbed of crime during a press conference. The neighborhoods bordering Page and Walton include Fountain Park and Lewis Place. City homicide statistics from this year show just two total between the two neighborhoods. 
 
 There has been a lot of violence in the neighborhood. This is the same intersection where a 93-year-old Tuskegee airman was carjacked this week. In July a 3-year-old boy shot himself in the head after finding a loaded gun inside a home on Walton. In June two people were shot in the 1200 block of Walton. A man was shot at the intersection of Page and Walton in March.

 The death also happened on the anniversary of the officer involved shooting of Kajieme Powell. Police say Powell was waving a knife at officers when they shot and killed him near a north St. Louis market. 
 
 About 200 demonstrators gathered in the area after the shooting. They were marching to mark the anniversary of Powell's death in downtown St. Louis. They are blocking the intersection despite several police orders to clear the road. 
 
 There are shooting witnesses being interviewed by police. The two officers who fired at the suspects are on administrative leave. They were not injured in the altercation. ||||| ST. LOUIS (AP) — The shooting death of 18-year-old Antonio Martin marks the third fatal shooting of a young black man by a white police officer in the St. Louis area since Michael Brown was killed in August.

 Here's a glance at the circumstances in each case: 
 
 ___ 
 
 MICHAEL BROWN 
 
 Michael Brown, an unarmed 18-year-old, was shot and killed shortly after noon Aug. 9 following an apparent scuffle in the middle of the street with Ferguson police officer Darren Wilson at his police vehicle. Brown's body lay there for hours as police investigated and an angry crowd of onlookers gathered. Several days of tense protests that sometimes turned violent followed in the predominantly black suburb, prompting Missouri Gov. Jay Nixon to call in the National Guard. St. Louis County prosecutor Bob McCulloch decided to present the case to a grand jury rather than appoint a special prosecutor. 
 
 The grand jury met 25 days over three months, and heard more than 70 hours of testimony from 60 witnesses before declining to indict Wilson in the shooting. The decision in November reignited unrest in the St. Louis area as well tensions between citizens and police across the nation. 
 
 ___ 
 
 KAJIEME POWELL 
 
 Kajieme Powell, 25, was shot and killed by St. Louis city officers on Aug. 19 after he moved toward them with a knife. Each of the two officers fired six shots. Powell died at the scene. 
 
 Police said Powell had stolen two energy drinks and a bag of doughnuts from a convenience store. They said the officers who responded to the call shot him after he acted erratically, refused to drop the steak knife and told them "Shoot me now. Kill me now." 
 
 The St. Louis police chief released 911 audio, surveillance video and cellphone video of the fatal shooting days later, acknowledging that tensions in nearby Ferguson had created a need for greater transparency regarding officer-involved shootings. 
 
 ___ 
 
 VONDERRIT MYERS 
 
 Vonderrit Myers, 18, was killed Oct. 8 when an off-duty St. Louis police officer shot him eight times. 
 
 The officer was working a moonlighting job as a security guard hired to patrol a neighborhood near the Missouri Botanical Garden in south St. Louis. Though not on duty, he was wearing his police uniform and armed with his department-issued gun. 
 
 Police officials said the officer became suspicious when Myers and the men with him started to run after he approached them. A chase ensued and the officer and Myers got into a physical confrontation. After Myers pulled away, police claim he started shooting at the officer. 
 
 Ballistic evidence released by police shows Myers fired three shots before his gun jammed. Police said they recovered the gun, which had been reported stolen in September. Myers' family contends that he was unarmed and that the officer mistook an object Myers was holding for a gun. 
 
 ___ 
 
 ANTONIO MARTIN 
 
 Antonio Martin, 18, was shot and killed by a Berkeley officer after police said Martin pointed a gun at him. 
 
 St. Louis County Police Chief Jon Belmar said the officer was questioning Martin and another man on Dec. 23 at a gas station about a theft at a convenience store in the suburb when the young man pulled a 9mm handgun on him. The officer stumbled backward but fired three shots, one of which struck Martin. 
 
 Belmar said the officer wasn't wearing his body camera and the dashboard camera was not activated because the patrol car's emergency lights were not on. The 34-year-old officer, a six-year veteran of the Berkeley Police Department, is on administrative leave pending an investigation.
– St. Louis police shot to death a black man today who allegedly pointed a gun at officers, raising tensions on a day when protesters were already gathering to mark the anniversary of another fatal police shooting, reports the Post-Dispatch.
