Daniel Young, 30, was on his way to work at Coventry University's London campus on January 19 when he was attacked as he used a popular commuter short-cut in Morden, south London.
His murder may be linked to an earlier, non-fatal stabbing of a 23-year-old man 1.5 miles away in Mitcham.
The clip shows the teaching fellow, dressed in a suit and carrying his laptop and a bag over his shoulder, walking along Dorset Road towards the entrance of Kendor Gardens.
He walked into the park at around 8am, and was stabbed within minutes. The first 999 call was made at 8.07am, Scotland Yard said.

There is still no clear motive, or reason, for what appears to be the senseless murder of a brilliant young man
Appealing for witnesses a week after Daniel's death, Detective Chief Inspector Cliff Lyons said: "Exactly a week ago today, Daniel left home to go to work.
"He had no reason to suspect he was going to be attacked and there is still no clear motive, or reason, for what appears to be the senseless murder of a brilliant young man.

"I believe his attacker left the park immediately after he attacked him and did so via the Dorset Road entrance. I am appealing for anyone who was nearby and saw something, however insignificant it may seem, to contact the incident room.
"The response from the public so far has been incredibly helpful and both I, and Daniel's family, are very grateful. However, we still need anyone who was in the vicinity of Kendor Gardens and Dorset Road at that time of day to get in touch."
