It's been almost one week since investigators announced the hunt for a serial stabber who authorities say is attacking men walking alone late at night in the Flint area.
The stabbings, five of them fatal, are scaring residents who think they've seen the attacker. "He was white, just like that description you all got," said a scared Flint resident who declined to give TV5 her name.
Since releasing the sketch, the Michigan State Police tip line has been flooded with calls. "Some, when they come in, appear to be very credible and it requires immediate follow-up," said Michigan State Police Lt. Pat McGreevy.
McGreevy is the head of the task force assigned to the case, and said that could mean the serial stabber stalked other victims but got spooked. "We've talked about that, but honestly, at this point we don't have any other information reported now to indicate that there are any other victims," said McGreevy.
So far, the stabber has attacked 16 men around Flint, killing five of them. All but two of the victims have been African-American.
Survivors told police their attacker is a white, muscular male with light-colored hair, and is driving a green and gold SUV, similar to a Chevy Blazer or GMC Jimmy.
Three similar assaults have been reported in Leesburg Va., and one in Toledo, Ohio.
Seven different police agencies and 14 investigators are dedicated solely to tracking him down before he strikes again.
"There's just so many similarities that we have to sort through, victims statements and reports, so this can be very tedious," said McGreevy.
Tuesday TV5 learned the FBI is on board, helping the task force sort through reports and respond to calls.
They have pretty easy access to go ahead and to reach across the state lines, said McGreevy. And besides, they have field offices all across the U.S."
Anyone with information regarding the investigation is urged to call the tip line at 1-866-246-9500.
Meanwhile, some local organizations are doing everything they can to keep some of the community's most vulnerable people safe.
For the last 90 days, James Lowder has been staying at the Carriage Town Ministries, a homeless shelter for Genesee County men just north of downtown Flint.
It is located on Garland Street, just two blocks from where the second stabbing victim was found. Now everywhere he walks, Lowder travels with a friend.
The shelter is doing its best to keep residents updated with information by posting the attacker's sketch, description and any new developments in the case.
