After two years spent living with a boyfriend in Georgia, Ana Racine returned home to Pasadena on Jan. 25, 2014.
Within hours, the 21-year-old was dead — shot in a Riviera Beach driveway shortly before midnight.
Sunday marked the one-year anniversary of Racine's death. Anne Arundel police are continuing to ask for the public's help in solving her murder.
Sgt. John Poole, of the Anne Arundel County Police Department's Homicide Unit, said Racine reunited with friends in the hours before her death. She had gone to Riviera Beach to meet a male acquaintance. A couple of other people were also there, Poole said.
Police dispatchers received calls just before midnight from those at the scene and neighbors reporting a shooting in the 200 block of Meadow Road. Racine died at the scene.
Poole did not provide information about the firearm used in the slaying, or details about Racine's injuries.
Even though there were witnesses, details about what happened remain scarce, he said.
"We're unsure if he (the acquaintance) was the target, or if she was the target. The motive for the killing is a question."
Those at the scene have cooperated with police, and there is no evidence indicating that anyone there was involved, Poole said.
Racine's boyfriend in Georgia has a solid alibi for the time of the shooting, the investigator said.
In the hours following the shooting, police canvassed the neighborhood and spoke with residents. Nearly a half-dozen residents reported seeing a dark-colored minivan speeding on Meadow Road seconds after the shots rang out. Police are still searching for the van.
Investigators have interviewed dozens of people in the past year, Poole said.
Racine had come back to Maryland to stay with her family, but it was unclear how long she planned to stay, Poole said. Attempts to contact them following the shooting were unsuccessful.
"We're interested in talking to anybody who saw her that day that we haven't spoken to," Poole said. "It's always difficult when these cases aren't solved right away, but we never stop. For us, it's still a fresh, active case."
Police are also continuing to search for the person who shot and killed Javante Parker, 21, of Glen Burnie, on Nov. 14, 2014, on Huff Court in Pasadena's Freetown community.
Parker's death is the only other unsolved homicide investigated by county police last year.
In January 2012, Gregory Sears, 36, was shot and killed in the driveway of his Laurel townhouse in another unsolved homicide.
Wednesday marked the four-year anniversary of the killing of Myra Cason, which also remains unsolved. Cason, 63, a retired county school teacher, was found shot to death in her Suzuki Sidekick in the parking lot outside of Gavigans Furniture in the 7300 block of Ritchie Highway in Glen Burnie in 2011.
So far in 2015, the county has had one homicide, that of 27-year-old Breon Cager in the 7800 block of Coutros Court, not far from where Parker's death occurred in Freetown. Family members said the two were cousins.
Anyone with information relating to any of the unsolved cases is encouraged to call investigators at 410-222-4700. Information can also be provided anonymously by calling the Metro Crime Stoppers Hotline at 1-866-7LOCKUP.
