The Austin Police Department has identified a new suspect they say was involved in the 6th Street mass shooting that killed one and injured 14. The suspect, 19-year-old De'Ondre Jemirris White, is still at large.

Authorities are dropping charges against 17-year-old Jeremiah Roshawn Leland James Tabb and a 15-year-old, who were originally arrested last week. They were taken into custody for aggravated assault causing serious bodily injury and deadly conduct, respectively. Police have since determined that they were not responsible for the injuries and death that occurred.

The investigation is still ongoing and Interim Austin Police Chief Joseph Chacon said based on witness interviews, ballistic evidence and video evidence, they were able to confirm that White fired the shot that killed 25-year-old New York tourist Douglas John Kantor.

"When he is apprehended, he will be charged with murder," District Attorney José Garza said.

An arrest warrant was issued last night for White, who remains unfound, though police know he changed his appearance and went into hiding in Killeen after he was interviewed. Police consider him "armed and dangerous." They have yet to determine whether or not shots were fired from both parties.

Police said the incident was a culmination of a disagreement between two groups from Killeen, resulting in the shooting. Police said after the shooting, Tabb and White, who was in the same group as Tabb, "fled to an apartment" and "discussed the shooting."

Police said many of the people in both groups had guns. Police have seized the handguns from suspects, which are now evidence, and said White's weapon has been connected to several violent crimes.

No final decisions have been made as of now but Garza said it will be in the best interest of the prosecution to release the two teenagers at this time. Tabb remained in the Travis County Jail until Tuesday morning for his assault charge. Garza said when the time comes, the district attorney's office will evaluate all of the evidence and make final charges.

Police are still asking for the public's help in locating White. Police ask anyone who comes in contact with the suspect to call 911.
