Passport to murder - Ali Bracken

As the country's murder rate has soared, a remarkable number of non-Irish nationals have met brutal deaths. Ali Bracken examines several cases in-depth, including:

Swiss student Manuela Riedo. Her killer, Gerald Barry, had a history of sexual violence against women, but was free to roam the streets.

Paiche Onyemaechi, a Malawian mother-of-two who was beheaded in a ritual murder. She was working as a prostitute, and her on-the-run husband is the chief suspect.

The screwdriver murders of Polish mechanics Pawel Kalite and Mariusz Szwajkos by teenage killer David Curran.

Inga-Maria Hauser, a German backpacker raped and killed in County Antrim. Police are hopeful that recent DNA advances could mean her killer's days are numbered.

Rwandan Regina O'Connor was brutally murdered by her drug-addict son Moses.

Belinda Pereira, an Englishwoman working as a prostitute, was murdered by a man who visited her for sex in an unsolved killing that baffled garda. A fresh look at the murder is now being considered by the Cold Case team.

The tragic murder of Indian businessman Sukhdev Singh by his friend Ram Pal, told here for the first time. Before he could stand trial, Pal died in prison.

The killing of Farah Swaleh Noor by the 'Scissor Sisters' is infamous, but what about the life and crimes of the Kenyan before his gruesome death?

The execution of Latvian Baiba Saulite by a Dublin crime gang on the orders of her imprisoned husband.
