UPDATED — 12:58 p.m.

Police say two people have died and three others have been injured in two separate shootings last night, bringing the total number of shootings in Chattanooga this holiday weekend to 10.

Police say last night's shootings may be connected and gang-related.

In the early hours of Tuesday morning, Chattanooga Police Chief Fred Fletcher said during a press conference that the reasons for gang disputes are myriad, "and they're often very trivial."

"That's what makes it so tragic to our community," Fletcher said. "People aren't fighting over things like the reason this Fourth of July holiday was built to celebrate which is, fighting for the freedoms of their community."

The first shooting occurred on the 1000 block of Jarvis Avenue where police say 28-year-old Marcus Cal was fatally shot after multiple people exchanged gunfire.

Tony Jackson and Ivan Hill, both 25, also were shot and transported to the hospital in personal vehicles. Both received non-life threatening injuries, according to police.

Witnesses reported that two vehicles shot numerous rounds at a group standing outside, Police said. But no suspect information was provided to investigators.

The second shooting took place on Woodmore Lane where 28-year-old Alex Freeman died from a gunshot wound to the chest..

Martin Jackson, 26, was also shot and received a non-life-threatening gunshot wound to the right arm.

Witnesses told police they initially thought fireworks were still being shot off, and ran when they realized it was gunfire. They said multiple rounds were shot from the passenger side of a black four door sedan.

Police say none of the witnesses could provide a description of the suspects involved.

Anyone with information is asked to contact Chattanooga police.
