"I lost three brothers from the streets and so I'm just fed up," said Odette Young, the sister of one of the victims.
Young says someone shot and killed her brother, 36-year-old Mario Thomas of Oakland Monday afternoon as he was sitting in a chair behind a laundromat. The family created a memorial at the scene. Thomas had two children.
"They lost a good father too," said Thomas' brother.
The Oakland Police Department says they received a call around 4:10 p.m. Monday for a reported shooting on the 7100 block of International Avenue. Upon arrival, officers located Thomas suffering from fatal gunshot wounds.
Oakland Police say Monday afternoon's homicide may be connected to one from Sunday night just across the street.

"He was a good man a great man, he was quiet, stuck to himself, took care of his kids and everything," said the woman.

"This level of violence in unacceptable," said Acting Chief LeRonne Armstrong.
Just last week, the Oakland Police Department announced it had reduced shootings and murders by 52-percent since 2011 as a result of a 7-year ceasefire program.
"What we're trying to accomplish is actually getting ahead of violence and being able to stop it before it happens," said Captain Ersie Joyner.
OPD says they believe their strategy is still working.
"We don't need to be killing each other, we don't need to be fighting each other, we need to pull together and look out for each other," said Young.
