(01/31/17) - (UPDATE) - Otis Smith and Anthony Holloway were formally charged Tuesday for shooting and killing two men in a Walmart parking lot Friday.
Michigan State Police say the two men found dead were killed during a Craigslist transaction.
State Police say 31-year-old Joseph Carson and 39-year-old Anthony Hammond traveled to Owosso to sell marijuana to the two brothers, Holloway and Smith, from Grand Rapids.
According to investigators, during the transaction the brothers, ages 23 and 31, decided to rob Carson and Hammond of the marijuana.
During the robbery the two Flint men were shot and killed.

Police have released the ages of the two men found murdered in a vehicle.
One of the victims is 31-year-old Joseph Michael Carson. The other is 39-year-old Anthony Lee Hammond. Both men are from Flint.

No arrests have been made.
(01/27/17) - The call came into police a little after 5 p.m. that there were two people dead in their vehicle.
We know the two are men.
Police have been focusing on a white SUV in the parking lot.
There were reports of blood on the outside the car.
We saw a few officers out in the parking lot inspecting each of the cars with their flashlights for any evidence.
It's not clear how long the car has been here.
And still no answers on how the two people inside were killed - if they were killed inside of the car or put there after being killed.
But Michigan State Police are calling it a double homicide.
The crime lab made its way out here to investigate around 9 p.m. They're trying to piece those details together.
This whole situation has been a shock to the Owosso and Corunna communities.
We've actually seen a number of people drive up just to find out what's going on.
And employees at stores close by tell ABC12 News they're nervous.
"We're gonna be doing some figuring out and seeing what we should do and talk to authorities. Maybe to see if it's safe here to come back and open in the morning," said Ashlee Whipple who works at Maurices.
"It shouldn't really happen here. This is just a small town and never heard about this or seen it before," Trever Reich said. His dad, Gary Wilson Gage added, "Just kind of shocked, you know, especially here at Walmart. You never expect something like that here you know with all the employees coming in and out of here, too. You know it's just - I'm shocked."
Michigan State Police say they don't believe there is a threat to the public at this time.
Again we're working to find out more details and we'll bring them to you as soon as the investigators can share more.
