The man told the ACT Supreme Court on Wednesday that the mother-of-three was usually ''very reliable'' and would call if she was running late.
His concerns led to him going to her Macgregor home to investigate, and the discovery of her lifeless body on a single bed in her bedroom shortly before 4pm on March 28, 2012
She had suffered 11 stab wounds.
Ms Conlon's boyfriend, Aleksander Vojneski, 31, is accused of her murder on the night of March 27, 2012.
He has pleaded not guilty and is on trial in the ACT Supreme Court.
Vojneski – who the Crown says is a volatile drug user with a history of knife crime – is alleged to have murdered Ms Conlon, 30, at the northside home after his attempts to get drugs had failed.
The pair met at a psychiatric ward in October 2011 while Ms Conlon was recovering from a marriage break-up.
The Crown says Vojneski had been admitted for treatment after suffering an alleged drug-induced psychosis.
On Wednesday, the court heard from the man who found Ms Conlon and reported it to police.
The man said concerns for Ms Conlon had mounted during the day after she missed several appointments and failed to respond to phone calls.
He told the court it was unusual for her not to show up without calling.
''I knew something maybe wasn't right,'' he told the court from the witness stand.
He went to her home and knocked on the front door.
He told jurors he could hear voices so he went through a side gate to check the rear.
He discovered the voices had come from a neighbouring property and had no luck when he checked the back sliding door.
He then used a key to enter the house through the front door. He called to see if anyone was home but received no reply.
The man said he opened Ms Conlon's bedroom door and noticed the double bed was empty.
He moved to leave when he spotted Ms Conlon lying dead on a nearby single bed.
He tearfully told jurors he immediately knew she was dead and left the house to call police.
The man wept as his triple-0 call to police was played in court.
During the call, he told the operator Ms Conlon had blood on her face.
Paramedics arrived first and entered the home.
A paramedic told jurors he knew Ms Conlon had been deceased for some time when he saw her and that she had most likely died an ''unnatural death''.
One of two police officers to arrive soon after reported seeing blood on the floor and the door handle of Ms Conlon's room.
The trial before Justice John Burns continues on Thursday.
