CHATTANOOGA, TN (WRCB) -- Six months after a teenage boy was gunned down in Chattanooga, his mother still doesn't have answers about his killer. For the first time, she's opening up about his murder.

Monterrius Rollins' mother says there's nothing she could ever do to bring back her son. Now, she's focusing on the future for herself and for his younger sister.

"We were about to go to the store -- just relaxing in the car, and one of his friends pulled up and said that he had to tell me some bad news. [Monterrius] had been shot!" says Ericka Holmes.  

That day changed her life forever. Friday, October 5, 2012: the day her only son -- Monterrius Rollins -- was shot and killed on Arcadia Street in Chattanooga.

"I had a feeling I knew where it had even happened. When I pulled up there was the tape and all the reality kinda set in like this really did happen."

Six months have now passed. Holmes says there's not a day that  goes by that she doesn't think about her son.

"There are those times when you see some of his friends or you pass by the bedroom door, which I've kept it closed, and when you see a picture. There are those constant reminders."

Monterrius was a graduate of Tyner High School and was enrolled in Chattanooga State.

Holmes doesn't believe her son was in a gang, but says she often questioned his friendships and the neighborhoods where he would hang out.

"I would beg him, 'It's just not a good area.' But he would always see the best in people."

Holmes is a single mom. She says she was always very involved in her son's life. Instead of focusing on what she lost, she reflects on all she had.
"I'm thankful for the 18 years . I'm thankful that he graduated from high school, so I try to stay focused on the positive."

Holmes says she hasn't spoke with police since her son was murdered and has no idea who killed her son.

"I don't know who did it to him, and I can honestly say I don't care about who did it to him."

But, she does have a message for the person who gunned down her son.

In that moment you probably thought you were punishing him. You're punishment for him ended there. You've affected hundreds of people. Anyone that's ever met him are the people that are suffering and that are missing out."

Holmes is currently a case manager for underprivileged children. She has plans to help other mothers and children that have gone through a similar situation.
