The 43-year-old former senior Continuity IRA figure was gunned down in broad daylight in the Peter Pan complex on the Springfield Road on Friday afternoon.
Police said he was working at the fuel depot business of a family friend, sitting in a portable cabin office, when he was shot through the window a number of times at close range.
He was hit in the upper body and was pronounced dead at the scene.
A man, who was detained on Saturday morning, has been released by police.
"A 26-year-old man arrested in the west Belfast area yesterday morning by detectives from Serious Crime Branch investigating the murder of Thomas Crossan has been released unconditionally," a PSNI spokesman said on Sunday night.
The PSNI said Mr Crossan, who was from west Belfast, was known to police and detectives have not ruled out a dissident republican feud in relation to his murder.
A red BMW car, which was set on fire at nearby Beechmount Grove, was discovered after the fatal shooting and a link is being investigated.
Appealing for information, police said they have set up an incident room for the murder.
On Saturday, Detective Superintendent Jonathan Roberts said: "Those responsible for this ruthless murder will only be brought before the courts and put behind bars if people with information work with police."
Members of the public can contact the special incident room on 02890 259542.
