All he wanted was a glass of milk.

Richard Blake is accused of breaking into a couple’s home as they slept, stabbing the husband and cutting the wife’s throat, then fleeing police in their SUV and on foot before being found by a tracking dog up a tree.

But Blake, 23, told a jury Monday on charges including attempted murder that it’s all a mistake.

His troubles began as walked to Mac’s Milk early in the morning on June 26, 2010 — he woke up thirsty and doesn’t like water — and a stranger whose face he can’t recall suddenly hugged him and offered him a free car.

Blake conceded it was “a bit naive” but his excitement won out and he agreed to take it and ran back to his Baseline Rd. apartment to pack so he could drive to visit his family in Campbellford.

When he came out, he found the SUV with the keys on the hood but the man was gone. He got in and drove off towards Hwy. 417.

He “started panicking” when he saw bloody knives and surgical gloves in the car but “rummaged through” the items.

He saw police cars coming up fast behind him, they boxed him in and “contact was made.”

“I was still kind of freaking out,” Blake said. “First I find the bloody knives then I’m getting surrounded by cop cars.”

He went off the road into the ditch and got back on the other way but something was wrong with the vehicle.

On “autopilot,” he stopped, hopped out and ran through a field and trees.

Then “my brain started working - why am I running? I have nothing to run from. I’ve done nothing wrong. I just ended up stopping and waiting.”

Some flies started buzzing in his face.

“To get out of them, I climbed up a tree,” Blake said.

Both Francois Renaud and Amalle Thomas identified Blake as the bizarre stranger who broke into their west end bungalow as they slept and terrorized them for hours.

Renaud said he was stabbed about 20 times, Thomas said she was duct-taped to a chair and her neck cut three times.

The jury has heard that Blake and both victims’ DNA was found on a box cutter found in their stolen SUV.

The trial continues Tuesday.
