Police in Oklahoma say it's too early to call the murders of three black men a hate crime.
The men were killed Friday during a shooting rampage in predominately black neighborhoods in Tulsa. Two others were wounded in the melee.
On Sunday, authorities arrested 19-year-old Jacob England and his roommate, Alvin Watts, 32.
Police say England may have been trying to avenge his father's shooting death by a black man two years ago.
The shootings have spread fear and anger in the city's black community. Local and federal authorities stopped short of saying the killings were racially motivated.
"It sickens you and it angers you," Chief of Police Chuck Jordan said. "This is not what Tulsa, Oklahoma, is about."
"It is very premature to talk about hate crimes; we have yet to analyze all the information," FBI Special Agent James Finch said.
The two men will be charged with three counts of first-degree murder and two counts of attempted murder.
