Police arrest suspect in March shooting death of shoe store worker A witness told detectives that after pushing away the brown sawed-off shotgun, Williams walked toward the gunman and that "within seconds," the witness "heard one gunshot and observed the decedent holding his chest and collapsing to the ground." District police announced Wednesday night that they had arrested Deandre Shaheed, 18, of Northeast Washington, and charged him with first-degree murder while armed. He was ordered detained until a preliminary hearing scheduled for June 27 in D.C. Superior Court. Court documents show that police also had previously identified two other suspects connected to the robbery, information not previously revealed. One man is being held on several gun charges linked to the shotgun, which police said in court documents was found in his possession. Another man who police said assisted in the robbery has not been charged. At the time of the attack, authorities said they did not know of a motive. Williams's relatives said they believed he was robbed, a claim that was backed up in a detailed account of the killing provided in court documents justifying the arrest of Shaheed. Police said three men were watching, and at one point following, Williams as he walked home from the Deanwood Metro station. Video surveillance cameras captured them as they walked along Lee Street Northeast, a block away from the victim's apartment, according to the court documents. One man was seen breaking away from the group and taking another path that police said was intended to cut off the victim and box him in. But police said the final confrontation occurred at the door leading into Williams's apartment building. Relatives for Williams could not immediately be reached Thursday morning. The Rev. Althea Smith-Withers, who baptized Williams and counseled at the Pavilion of God church in Northwest Washington, also could not be reached Thursday morning. But the church posted an update on its Facebook page: "Praise God!! Someone has been charged in the murder of our Beloved Olu Williams... this is just Step 1... please continue to be prayerful! Williams had graduated the previous December from Catholic University with a bachelor's degree in interdisciplinary studies and was taking graduate-level courses preparing for law school. Williams had been a manager of a shoe store, but returned to sales to free up hours for school, his family and minister had said earlier. He was working at Comfort One Shoes at the time of his death. His brother worked at a shoe store across the street, and the two usually commuted together. But relatives said on the night of March 14, Williams wanted to leave early and took the Metro home. His father was a Howard University professor, and family members said Williams grew up listening to public radio and that library books supplanted electronic entertainment. He was a graduate of Wilson High School and enjoyed discussing Henry David Thoreau.
