Family and friends of Isaiah Garcia gathered Tuesday at Mount Olivet Cemetery to mark what would have been his 19th birthday.
In the early morning hours on March 23, someone came to Garcia's front door and shot him at close range.
The murder remains unsolved and police say leads in the case have stopped coming in.
Garcia's family is desperate for closure.
"He never goes out of my mind. I'm thinking of him every second," his brother Isaac Garcia said.
Garcia was inside the apartment on the 1300 block of Knox Court, near the intersection of Colfax and Federal, when Isaiah answered the door and someone pulled the trigger.
"I can still hear the gunshots. I can still hear everything," Garcia said.
Garcia watched helplessly as his older brother died.
Now he is watching his young nephew Xavier grow up without a father.
"Every time I look at him, he does something that reminds me of Isaiah. And I just start crying," Garcia said.
The family's tears are still flowing but investigator's leads have dried up.
According to his father Manuel Garcia, the teenage dad was just out of jail on a juvenile probation violation and was determined to stay out of trouble.
Denver police suspect gang activity, which means the people who know what happened often stay quiet.
"No one's come forward. Have a heart. Come forward. Give us some closure," Manuel Garcia said.
Every day the Garcia family hopes for a break in the case.
They also treasure the time they spend together as a family, like an outing Saturday at Sloan Lake in Denver.
"Isaiah is up there making this day beautiful for us. He wants us to have a nice day," Isaac Garcia said.
Denver police consider Isaiah Garcia's murder an open and active investigation.
They've followed a number of leads but none of them have panned out.
