The parents of Michael Brown, the unarmed 18-year-old who was fatally shot by a police officer in Ferguson, Missouri, will attend a rally in support of Eric Garner, the Staten Island man who died after being placed in a chokehold by police last month.

Around 15,000 people are expected to attend the Saturday demonstration. Participants will start near the area where Garner was killed and will then head toward the Staten Island District Attorney's office to demand justice. The march will symbolically link the deaths of Brown and Garner to shed light on harmful policing strategies and patterns of racism by police forces across the country. 

"There's a pattern here. And the pattern is a predisposition toward disproportionate force, toward violence, on Black men," Rev. Jesse Jackson told The Wall Street Journal during a telephone interview from Ferguson.
