Police say Rigoberto Vargas arrived home after a long day of work in construction, ready to play with his 7-year-old daughter.
A man ambushed Vargas as his little girl opened the door to greet him. The girl watched her father get shot three times in the back, police say.
They say Vargas died in front of his daughter, his common-law wife and brother. Another person in the apartment, who police did not want to identify, was also shot, but survived.
For four months, detectives have searched for Vargas' killer. Many leads have been exhausted and say they need the public's help.
Investigators released new video of the suspect Thursday, the day before the four-month anniversary of Vargas' murder. The video shows a man in a navy blue T-shirt running from Vargas' apartment.
Police say surveillance video from the washateria next door shows the suspect waiting in bushes for nearly an hour before Vargas arrived home.
Minutes before the murder, detectives say the man put on blue latex gloves.
Police don't have a motive and say Vargas wasn't robbed. His brother, Jose Sarmiento, says Vargas was a hardworking man who kept to himself and spent what little free time he had with his family.
"It really hurts," said Sarmiento in a news conference Thursday via a Spanish translator.
"His 7-year-old daughter opened the door and saw her father take his last breath," said Alex Vinogradov, a detective on the case. "Let's get justice for her."
