Two men have been found shot dead in a car parked on an industrial estate.
West Midlands Police said they have launched a murder investigation after the men were discovered just before 3.30pm on Wednesday.
However it is thought the victims, who have yet to be formally identified, were killed at the site in Brierley Hill, Dudley, shortly after 1pm.
The car they were in was parked outside units off Moor Street, and the area has been sealed off while forensic investigations are carried out.
West Midlands Ambulance Service said it had been called to the scene at 3.30pm on Wednesday, sending an ambulance and paramedics.
A spokesman said: "On arrival, crews discovered two male patients, both of whom were inside a car.
"It is believed they had been there for some time.
"Unfortunately, it quickly became apparent nothing could be done to save either of them and they were confirmed dead at the scene."
Detectives are now appealing for anyone in the area at the time who may have seen or heard anything to get in touch.
Residents living in the area around the Albion Works industrial estate said they heard nothing untoward on Wednesday afternoon.
The site is fringed by another industrial park, a canal, a disused railway line and a footpath linking Moor Street to a nearby housing estate.
A police van blocked the single entrance to Albion Works on Thursday, moving only to allow access to other police vehicles, including a forensics unit.
A man who lives near the site, who declined to be named, said: "The police were cordoning off the path when I got home from work but my dad was in all day and he heard nothing.
"You can see the back of the industrial estate from the path. There's units and a scrapyard-type thing at the back there."
Another nearby resident said: "I only know what I've heard on the news. I didn't hear a thing.
"It's frightening really that something like that has happened."
