Silent Witness was Hong Kong’s star racehorse who won his first 17 sprint races in Hong Kong. He was ranked the world's top sprinter for three seasons.

Foaled in 1999 at Taree, New South Wales, Australia, Silent Witness is by El Moxie (USA) out of Jade Tiara by Bureaucracy (NZ).

Silent Witness was trained by Tony Cruz, ridden by Felix Coetzee and owned by Mr. and Mrs. Arthur Antonio da Silva.

He made his debut as a three-year-old at Sha Tin in a 1,000 metre race and won by a margin of almost four lengths in the fast time of 57.8 seconds.

In the Centenary Sprint Cup (G1), Silent Witness equalled the long-standing Hong Kong record of ten consecutive wins.

He won the Hong Kong Sprint at HKIRs in 2003 and 2004.

After the 17 consecutive wins, he attempted the mile race in the Champions Mile on May 2005 at Sha Tin  but he was defeated by Bullish Luck by a short head.

He made a second attempt on the mile by going to  to participate in the Yasuda Kinen in June but was defeated by Asakusa Den'en near the winning post.

In October 2005, he took part in the Sprinters Stakes, a Group 1 Sprint Race in Japan over 1,200 metres and won easily by 1¼ lengths with a time of 1:07.3 seconds, only 0.3 seconds slower than the track record time.

For the three years from 2003 to 2005, the International Federation of Horseracing Authorities in Paris ranked Silent Witness the world's fastest sprinter.

Silent Witness is sometimes compared to another Hong Kong champion, Co-Tack, and the American horse Cigar who won 16 consecutive races.

Silent Witness was retired after his last race on the Sha Tin on 4 February 2007. He is now at Living Legends, the International Home of Rest for Champion Horses at Greenvale, Victoria, Australia.
