A man shot and critically wounded by police to end a Melbourne siege is yet to be interviewed over an earlier fatal stabbing.
The 45-year-old man is under police guard in The Alfred hospital as homicide detectives take over the investigation into the stabbing in Seaford, in Melbourne's south on Monday morning.
Police say the victim, a 46-year-old Seaford man, was stabbed at one address, then staggered to a second location before he was taken to hospital with life-threatening injuries.
He died in hospital on Tuesday afternoon.
Police, seeking to question the Frankston man, located him at a house in Frankston about 5.30pm on Monday, sparking a stand-off that lasted almost 14 hours.

Heavily armed police stormed the house about 7.20am because the man began stabbing one of three women he had threatened to kill during the stand-off.
Police insist they saved the woman's life when they fired on the man, who was armed with knives and who they had been negotiating with through the night.
Victoria Police Assistant Commissioner Robert Hill says they first hoped the siege could be resolved peacefully. But he said the man became increasingly irrational overnight, threatening to kill the three women and a man who were inside.
"My understanding is that the ice that he may or may not have used yesterday was starting to wear off and his behaviour deteriorated," Mr Hill told reporters.
Then the man stabbed a 37-year-old woman and police opened fire, striking the 45-year-old, and ending the siege.
"He stabbed her in the leg, he commenced to, we believe, go down a path where he was going to take her life. So we intervened and we saved her life," Mr Hill said.
Minutes later the bloodied Frankston man was wheeled out on a stretcher to a waiting ambulance.
The injured woman was taken to the Frankston Hospital and is in a stable condition. The man also assaulted a second woman in the house.
"She has been slashed on the hand and also suffered a blow to the head, a punch, from the offender," Mr Hill said.
She, two other women, aged 44 and 32, and a man aged 65, from Frankston, who were in the house have been speaking with police about what happened.
