"It's very, very brutal," Homicide Capt. James Clark said at a news conference yesterday afternoon. "It would appear to be very, very personal."
Crump's gruesome remains were found shortly after 7 a.m. by construction workers at the site of the former Black Red White furniture store, on Northeast Avenue near Serota Place, in Bustleton, across the street from George Washington High School's ball fields.
Clark said investigators believed that Crump, who graduated from George Washington in 2012, was killed about 5:30 a.m.
It was unknown how the young man ended up at the construction site, or if he had been abducted.
Clark said Crump was last seen leaving his job at Wendy's, on Red Lion Road near Haldeman Avenue, about 11 p.m. Saturday. Employees at the restaurant declined to comment last night.
Crump sometimes lived with his mother and grandmother, or with a girlfriend or other friends. It's unclear where he went after finishing his last shift at Wendy's.
Clark said Crump didn't have a criminal record or prior contact with police. Investigators were looking into the possibility that he had recently been threatened, although the nature of the threat was also unclear.
The captain said it did not appear that Crump had been robbed.
Crump's mother, Sherron Kaba, said her son was smart, funny and energetic. The two shared a birthday, Oct. 29.
"He was just very, very caring," she said tearfully in a brief telephone interview. "He was a good kid and we miss him."
Kaba said she was not aware of any trouble her son was in or why anyone would want to harm him, adding, "He was good. He was caring."
She noted that Crump wanted to attend college to study business. He played varsity basketball for George Washington during the 2010-11 school year, and scored two points in a game against Olney High School.
"He wanted to have a clothing business," Kaba said.
