Five of the weekend victims were shot in a four-block stretch of Northwest Baltimore, and police officials said the incidents appeared to have little in common beyond their geography.
On Monday, Virgil Martin wore work gloves, work boots, sunglasses and a floppy camouflage hat as he raked up trash on the sidewalk and gutters outside the Private Stock Social Club, a gray, windowless building at the corner of West Belvedere and Arbutus avenues.
He lives on the block, and at about 1:30 a.m. heard the shots and began filming on his cellphone camera from his second floor window as more than a dozen police cars arrived. The officers would find three men wounded by gunfire.
"They need to start some chilling and stop the killing," he said. "They're shooting each other over nothing."
As he picked up trash, Martin said the city doesn't seem to want to invest in the area. Martin has lived in the neighborhood since 1968. Teens and young men have nothing to do, he said. There are no jobs. Budget woes have closed some of the city's recreation centers. He said officers need to get out of their cars and get to know residents.
A half-block away, Angela Simonson spoke through a screen door about the apathy that seems to surround the block, where residents feel resigned to the violence. She said she heard 13 shots Sunday night.
"What are you going to do? I'm not used to it, but you have to be, living here," she said.
A handful of houses down, two homicide detectives studied a fresh memorial that had sprung up, with candles still burning in the hot sun near the carport of a boarded-up house. It was where Omar Shorter, 32, was killed about 11:30 a.m. Saturday.
A crime scene technician waved a green metal detector around the shrine, then stopped to look closer in the grass.
"I found a bullet," he said.
In another shooting in the area, 53-year-old Claude Nelson was shot dead in the 5200 block of St. Charles Ave. He joined Jones, Shorter, Andre Witherspoon, 27; Danquel Darden, 37; Maurice Taylor, 37; and 49-year-old Joyce Alston — who was shot along with Burgess — among the weekend's dead. At least one other victim was listed in critical condition.
At Clarinda Academy in Iowa, Burgess stood out to Knight as one of his more coachable players. "He spent more time trying to help players around him than maybe himself," Knight said. "He wanted to win, but he understood there was more to it."
Knight coached at Clarinda Academy until last year. He called Clarinda, which describes itself as a residential foster care facility for at-risk youth, a "prep school for kids who had made bad decisions in their past."
Youths came from across the country, but Knight said there were a high number of youths from Flint, Mich., and Baltimore, and they were some of the most personable kids. They were also the ones he worried about the most.
He once accompanied a student who was returning to Baltimore. "I've been a lot of places and never been uncomfortable," he said. "And I was uncomfortable."
Court records show Burgess got in trouble once back in Baltimore. First it was minor things, like trespassing and playing dice.
In May 2012, police said, "concerned citizens" called to complain about men selling drugs in the alleys and vacant buildings of the 1500 block of N. Monroe St., according to charging documents. Police on the scene said they observed Burgess handing out heroin gel caps to several people while another man collected money from them.
Burgess was found guilty and sentenced to five years in prison, with all but about three months of the sentence suspended. On Jan. 9 of this year, he was arrested and charged again with selling drugs and resisting arrest and had an open warrant at the time he was killed for violating his probation.
Knight remembers who Burgess was, and who he could have become. He called the death "devastating."
"I will remember the enormous smile on his face every day," Knight said.
