Two people have died after they were stabbed Tuesday afternoon inside the Westfield Wheaton mall in Montgomery County, Maryland. The search for the suspect continues.
The two male victims were stabbed after they were involved in a fight on the lower level of the mall, near the Hollister clothing store, police said.
They were not identified immediately and their ages were not released.
Officers were called to the mall about 3:15 p.m. They found the two victims with life-threatening stab wounds.
A teenage girl who said she worked in the mall said she saw a "kid" who was attacked. His friends were trying to help him, she said, declining to give her name.
At least one person was questioned in the case and searched. Video shot from Chopper4 shows police stopping drivers as they try to leave the mall parking lot. Officers searched their backseats and trunks.
Police said surveillance camera images could provide valuable information as they work to confirm a description of the suspect.
Shoppers leaving the mall said they heard an announcement asking them to leave. Some stores were open and others were closed, a woman who answered the phone in the mall security office said.
The mall, also known as Wheaton Plaza, is located at 11160 Veirs Mill Road in Wheaton, Maryland.
Metro riders on the Red Line were told to expect delays in both directions due to an investigation at the nearby Wheaton station. Normal service was restored by 5 p.m.
Anyone with information for police is asked to call 240-773-5070. Anyone who wishes to remain anonymous can call 866-411-TIPS.
A reward of as much as $10,000 is offered.
