Brooklyn Woman, 27, Missing Since Saturday

Police are searching for a 27-year-old Brooklyn woman who was last seen leaving her parents' home Saturday night and failed to show up to her job the next day.

Sabrina Malone's sister said she saw her leave their parents' house in Cobble Hill at about 8:30 p.m.

"She said she was going home," said her sister Kiana Manning. "That's where I expected her to go."

By the next day, there was still no sign of Malone at her Crown Heights apartment. Her mother said she didn't show up for her shift the next day at IKEA, where she's worked for three years, and that she never called in -- something her daughter would never do.

Law enforcement sources said they could not find an electronic trace of the woman until Thursday, when detectives found her credit card was used in Washington, D.C.'s Union Station. Police are in the process of determining whether it was Malone who used the card.

Sources familiar with the investigation say detectives interviewed Malone's roommate and learned she texted him Saturday night, which authorities believe is the last known contact she had with anyone.

The sources say the missing woman texted her roommate because she was trying to get access to the apartment they share, and the roommate told detectives they only have one key.

Police searched rooftops and elevator shafts in the neighborhood where Malone disappeared, but have found nothing. Calls to her cell phone go directly to voicemail. The lack of contact and failure to show up for work is highly unusual for Malone, who is often in touch with family and hasn't missed a day of work in three years, law enforcement sources and relatives say.

"This is so unlike her," Malone's mother, Paul Manning, said. "If anyone has seen her or has any information about her, we're just asking them to reach out to us."

"It didn't really set in for me until I saw the flyers," said Kiana Manning, Malone's sister. "And I thought, 'Wow, no one knows where she is.'"
