HEAD of the Independent Commission of Investigations (INDECOM) Terrence Williams, fed up with the slow pace at which the police submits statements to the commission, says he will be presenting a report on the issue to Parliament within the next three weeks.

According to Williams, recent assessments showed that the level of compliance by the police in submitting statements in the first 10 hours of an incident was less than 50 per cent.

The Commissioner did not give overall figures of reported incidents from which the assessment was made, but said the concern was among a list of issues it would bring to the House's attention.

"Compliance with notices to give statements is over 70 per cent, but in terms of promptness, I would say this is under 50," Williams told the Jamaica Observer on Tuesday -- four days after last Friday's fatal shooting of three men in Shrewsbury, Westmoreland, allegedly by the police.

The dead men, who lived in the Shrewsbury Housing Scheme, have been identified as 28-year-old firefighter Andrew Brydson, his brother Triston Brydson, 24, and their cousin, 38-year-old chef Kingsley Green.

They had recently moved from Lacovia, St Elizabeth to Westmoreland. Residents of Westmoreland and St Elizabeth have staged several protests against the killings.

In a release to the media on Monday, INDECOM said notices were served on the officers involved in the incident, but that four days later the commission was yet to get a response from them.

According to the Commission, it had impressed upon the officers that their responses be made within a 10-hour time frame.

"The deadline was therefore set at 9:00 am Saturday, March 16, 2013. Efforts were made to collect the statements at the time set, but the men were not seen and the statements were not received," the release said.

INDECOM officials said attempts were made again on Monday, March 18, 2013, but the men could not be reached.

"The efforts continued today (Tuesday). We were told by the Superintendent that he had reminded the men about submitting their statements, and they said they would. We were unable to make contact with them today. The reason given is that they were in an administrative review at the Montego Bay Police Station," the INDECOM release stated.

However, addressing members of the media following a tour of Shrewsbury on Wednesday, Williams said the statements were ready to be collected.

"You might have known that they (police) had not up to (Tuesday), provided us with statements. I understand the statements are now ready for collection. It would mean that they are late and we have to look and see if there is any good reason for them to have been late and determine what we are going to do about that, if anything," he said.

So far, seven statements have been collected from eyewitnesses in the incident, station diaries have been copied, and the ammunition register from the Savanna-la-Mar police station has also been copied, said INDECOM.

Williams disclosed on Wednesday that an additional investigator from Kingston had joined his western Jamaica counterparts in the probe.

"The investigation is going quite well. What needed to have been done was done by the team, and it is just a matter of following up in these further hours," he stated.
