A 39-year-old man has been sentenced to life in prison for the murder of his wife at their home in Dublin four years ago.

Renato Gehlen, who is originally from Brazil, stabbed his wife Anne Colomines in Dorset Square, Gardiner Street Upper, on 25 October 2017.

He had pleaded not guilty but the jury at the Central Criminal Court rejected his claim that the 37-year-old French woman's wounds were self inflicted.

Mr Justice Michael McGrath described her death as terrifying, horrific and completely senseless.

Ms Colomines moved to Ireland and worked in Paypal. She met Gehlen who also worked in Paypal here and they married in October 2012.

However, in the months and weeks leading up to her violent death, the marriage was in very serious difficulty and she had told her husband she wanted a divorce.

He became very upset and wanted to "revive and repair" the relationship but discovered that Ms Colomines had met someone else in France in the summer of 2017.

On the night of her murder, she exchanged 296 messages with her new French boyfriend.

Thirty minutes after the last exchange at 11.06pm, gardaí and the emergency services discovered her body in her bedroom.

Her husband had stabbed her four times - one of the wounds was a 22cm incision to her throat. She also had cuts to her hands consistent with defensive wounds.

Gehlen told gardaí his wife had stabbed herself but the State Pathologist found this was "highly unlikely".

Last month, a jury took two-and-a-half hours to find him guilty of murder.

In victim impact statements read to the court today, Ms Colomines' family spoke of their loss.

Her father, Jean-Louis, said his heart is torn and living remains an ordeal.

Her mother Danielle said life has lost its meaning. It is not the role of a mother to bury a child, she said.

Anne's sister Alexandra spoke of the heartbreak and intense pain at the loss of her sister who she said loved life. "All this for what?" she asked.

Mr Justice McGrath said the murder was horrific, terrifying and completely senseless.

The fact that Gehlen sought to ascribe Ms Colomines' death to her own actions must have been all the more harrowing to her family to listen to, he said.

He sentenced Gehlen to the mandatory term of life in prison.
