Alvin Watts and Jake England, the two men suspected of the Tulsa, Okla., shooting are in custody and will be brought before the court on Monday on suspicion of first-degree murder.
Three people were killed and two others wounded on Friday in the incident that occurred in Tulsa's Africa-American community.
Police told the media that there were online posts that indicated that one of the suspects may have been trying to avenge his father's death.
England, 19, and Watts, 32, are being held at the Tulsa Jail on others complaints that include shooting with intent to kill and a single complaint of possession of a firearm while committing a felony, jail records reported by the media show.
The two were arrested on Sunday at a home in Turley, north of Tulsa, after a manhunt the FBI called Operation Random Shooter. They have not been charged as yet.
Tulsa Police Chief Chuck Jordan credited the Tulsa community for the arrest.
We were desperate for leads. That's why we made some very pointed requests for our community to come forward, he said. And they did.
Authorities have yet to establish a motive for the crime but said that it was too early to say whether the Tulsa shootings were racially motivated.
Police spokesman Jason Willingham told the Associated Press that Facebook postings that are believed to be England's show that there may have been a wish to avenge his father. England's father was shot and killed two years ago and a black man, Pernell Jefferson, was arrested as a person of interest in the case, the AP reported.
Reports were that the day prior to the shooting, England used a racial slur in a Facebook post.
Today is two years that my dad has been gone, shot by a f------ n-----. It's hard not to go off between that and Sheran. I'm gone in the head, the media stated that the post read.
But police won't be so quick to call the shooting hate crime because Jordan said the facts of the case can be looked at and certainly come up with what would appear to be a logical theory. But we're gonna to let the evidence take us where we want to go. There are motivations other than race in these kinds of incidents, and we're gonna look at it.
