GAITHERSBURG, Md. (CBSDC) — Police have arrested a man for allegedly stabbing a 7-Eleven store clerk to death with a box cutter during an unprovoked attack early Thursday morning in Gaithersburg, police say.
A second employee was able to run from the store, located in the 9000 block of Snouffer School Road, and call 911 as the attack began around 1:50 a.m., according to Montgomery County Police.
Police say Shaun David King, 36, was covered in blood and carrying a box cutter as he attempted to leave the store when officers arrived. He attempted to run, but was quickly taken into custody.
The 7-Eleven clerk, identifed as 63-year-old Abdul Ghaffar, was found suffering from multiple stab wounds to his neck, chin, and wrists, according to police. Ghaffar was taken to the hospital where he later succumbed to his injuries, police say.
Detectives are working to determine a motive for the attack, but do not believe King was attempting to rob the store.
It is unclear whether Ghaffar and King were familiar with each other.
The second employee was not injured during the attack.
Authorities say a violent crime of this nature is uncommon for the area.
King has been charged with first-degree murder.
