BOSTON -- A wake is scheduled for Friday in West Roxbury for a graduate student from Boston who was found slain in a deserted lot in New York City last weekend.

Friends and relatives of Imette St. Guillen, 24, will gather at the Gormley Funeral Home Friday afternoon to pay their respects, as detectives continue to search for clues in the gruesome murder case.

NewsCenter 5's Amalia Barreda reported that as St. Guillen's family prepared to bury their loved one, investigators in New York reportedly are coming up empty.

Investigators are reportedly without solid leads. Authorities in New York said they have no suspect and are asking for the public's help to find St. Guillen's killer.

St. Guillen had just returned from a vacation trip to Fort Lauderdale, Fla., before she was killed in New York City on Feb. 25.

Her naked, battered body was found wrapped in a bedspread in a deserted area of Brooklyn. The corpse was found after someone called 911 anonymously from a public phone outside a diner to tell police where it was located.

The New York Post reported the brief exchange with the tipster Friday.

Operator: "Hello, 911"

Caller: "I think there's a body over at Fountain and Seaview."

Operator: "How do you know? What did you see?"

Caller: "It looks like a body. You should send someone to take a look at it."

After the brief exchange, the caller hung up, police said.

Rewards for information leading to an arrest now total $42,000. The total includes money from New York City and the John Jay School of Criminal Justice where St. Guillen was a graduate student.

In a statement the family expressed their gratitude saying, "We are so appreciative it is beyond words. We are especially grateful because this reward may help to bring forward more individuals who may have seen something or have information that can help make sure that his devastation does not happen to another family or community."

St. Guillen's funeral is scheduled for Saturday morning in West Roxbury.
