Worker kills IT supervisor at business park

BALTIMORE, Maryland (AP) -- A shooting at a suburban business park left two people dead in what police are calling an apparent murder-suicide.

An employee and his supervisor were meeting alone Thursday afternoon in an office at BD Diagnostic Systems when other workers heard gunfire, said police spokesman Cpl. Michael Hill.

"Right now, we don't know what the motive was or what the meeting was about," Hill said. "This is a horrible event for all the people in this office."

Police identified the supervisor as Harold Creech, 59, and the employee as Morris Lyons, 52. Authorities would not say whether a gun was recovered.

Creech supervised the information technology department at the office, said Susan Glack, who acted as family spokeswoman.

The office park is located in the community of Sparks, about 20 miles north of Baltimore.

BD Diagnostics' Sparks facility manufactures instruments to test for infectious diseases, according to Colleen T. White, a spokeswoman with BD Inc. BD Diagnostics is a division of the larger company. (CNN)
