The two teenagers met online and were dating about a week when they started to run out of money.

“Somebody has got to get it,” one of them said to the other, referring to some cash.

So the two 17 year olds from suburban Maryland walked from the Motel 6 in Northeast Washington where they were staying to the Greyhound bus terminal in search of a cabbie to rob, according to charging documents filed in D.C. Superior Court.

Joshua T. Mebane of Waldorf and his girlfriend, Linda Bury, of Parkton, got into Quadar Muhammad’s cab and asked him to take them to Hamilton Junior High School at 1401 Brentwood Parkway, NE, according to the documents.

Before they left for the school, Mebane, sitting in the back seat with Bury, asked Muhammad how much it would cost. “Six-fifty,” Muhammad replied, the charging documents said.

Mebane then asked “Can you break a fifty?” Muhammad said yes.

When Muhammad pulled behind the school, Mebane reached into a black sports bag and pulled out a gun and shot Muhammad once in the back of the head, police said in the charging documents. The car accelerated, lunged over an embankment and crashed into a tree.

It’s unclear whether anything was taken from the driver.

On Saturday, Mebane and Bury were arrested and charged as adults with first degree felony murder while armed in Muhammad’s slaying.

Police were called to the scene at about 9 p.m. for the report of a late model Lincoln Town car on fire. When authorities arrived, they found a body, later identified as Muhammad’s, in the driver’s seat.

A day later, according to charging documents, D.C. detectives got a call from Baltimore police about a possible witness. The witness told police that Bury had told two others that she and her boyfriend “killed a cab driver,” the documents said.

Police initially questioned Bury. After several conflicting stories, according to the court records, Bury told detectives the details of the shooting. Mebane was later arrested.

At their hearing Saturday, Bury and Mebane were ordered held in D.C. jail until their next hearing on Jan. 20 before Judge Thomas J. Motley.
