Brian Sherry believes the gunmen did not know Anthony was in the house. They held him by the radiator, shot Marlow upstairs, then came down unmasked. Sherry thinks Anthony knew them from the inner city and could identify them, so the same gun was used to kill him.

Marlow's niece Elaine gave him tablets and a drink around 9 o'clock, then left for school. Plumber David Murphy left to buy equipment and, back at 9.28, rang Anthony because nobody answered the door. Sherry believes the shooting happened in that 10 minute window.

Very little. Investigators recovered the shell casing from the 9mm handgun, and Marlow had been shot six times. There was nothing around the bed or on the door handle. Clothing and footwear bought before the murder were traced to a buyer but never recovered.

Practically immediately. Two cars were seen after the shooting: a black VW Passat used in the murder and a second car following it. The Passat was burnt out in a lane off Ballygall Road East, but did not burn to a cinder, so it was forensically examined. Sherry believes three, possibly four, were involved.

Marlow was second in command to PJ Judge, known as the psycho, who was dating Marlow's sister. PJ Judge was shot dead in Finglas around 1996, and rumour had it Marlow set it up. From 96 on, Marlow was the kingpin and wanted to be Ireland's number one criminal.

His shipments started being seized and associates arrested with large consignments. His crew suspected a rat, but Sherry believes it was Garda surveillance. The crew came to believe Martin himself was informing on them, and he brought in Dutchie Holland to scare off would-be assassins.

Finglas had many major criminals and murders, and witnesses were intimidated. After one murder, Sherry saw two notable criminals making a hand-across-the-throat sign to people on the street. One Scribblestone witness said they heard the shots when no one else admitted it.

From 2002 to 2007 Sherry's district had 19 murders, about 20 or 30 attempted murders, shootings, bombings, drugs, rapes and burglaries. Two detectives were taken off his own staff to man the incident room, and NBCI help was pulled away to other crimes.

Sherry believes so. Many people who created fear in the area are gone or older, and witness statements remain valid years later. He says the case is very close and just needs a little help from the public, comparing it to the conviction for Nora Sheehan's murder.
