It was acid and he was shot.
A man whose body was found dumped on a street covered in "potentially hazardous" substances had been shot and attacked with acid, police said.
Liam Smith's body was discovered on Kilburn Drive in Shevington, Wigan, at about 19:00 BST on Thursday. Greater Manchester Police (GMP) has launched a murder inquiry into the "unique and shocking circumstances".
Following Mr Smith's death, his family paid tribute to the 38-year-old as "the life and soul of the party".
His body was found on a patch of rough ground between houses which leads to a dirt track and open fields.
GMP said: "Detectives are working tirelessly to establish the exact details of this murder, which took place in unique and shocking circumstances on a quiet residential street."
The hazardous substances were not believed to pose any further harm or risk to the public and have been contained, it added.
Det Ch Insp Gina Brennand said the "shocking murder of a much-loved family man" was the first fatal shooting in the area for more than two years.
She urged anyone who had seen "anything unusual or out of the ordinary near to the victim's home" on Thursday to contact the police.
"We are determined to recover the weapon and find Liam's killer," she said.
