Slain officer's partner mourns soul mate

Todd Robinson, the partner of Constable Humphris, who was tragically killed with three colleagues on the Eastern Freeway at Kew on Wednesday night, spoke to reporters out of a desire to make sure his soul mate of four years is remembered.

Mr Robinson was preparing dinner, expecting Constable Humphris to walk through the door, when he heard about a crash involving police members on the news.

He texted Constable Humphris, who had been in the force for less than a year, but did not get a reply.

Two hours went by and he saw confirmed reports four officers had been killed.

"At that moment I got a knock on the door with five senior police officers there," Mr Robinson said.

"My soul mate has gone."

The pair moved from NSW three years ago and Glen had decided, with Mr Robinson's encouragement to have a career change from carpentry to the police force.

"He loved helping people; being there if someone was in trouble and being supportive to the community," Mr Robinson said.

"He lit up the room when he walked into it."

Constable Humphris loved his job.

"In his breaks he would message me and let me know he was okay," Mr Robinson said, fighting back tears.

The couple had been settling into life in Melbourne with new friends and making plans for the future including a trip to America next year.

Mr Robinson said his partner wore a uniform, but was a person underneath.

"He came home to someone, and on that day he didn't," he said.

"He's gone and I'm still coming to terms that that door is not going to open."

Const Humphris along with Leading Senior Constable Lynette Taylor, Senior Constable Kevin King and Constable Josh Prestney died after being hit by a truck while dealing with Porsche driver Richard Pusey in the emergency lane.

Pusey allegedly ran off and was arrested on Thursday morning.

The truck driver had a medical episode afterwards and has been under police guard at hospital ever since Wednesday night's crash at Kew.
