Sounds like he’s one of the recent asylum seekers.

Italian police have arrested a Senegalese illegal immigrant who prosecutors believe killed Ashley Olsen, a U.S. woman who was found dead in her apartment in Florence last weekend.

“We have collected very serious evidence of his guilt,” Florence chief prosecutor Giuseppe Creazzo told reporters at a news conference on Thursday after the man was arrested and questioned in the early hours of the morning.

Creazzo said the man, named as Diaw Cheik Tidianee, had met the 35-year-old Olsen in a local nightclub and that the two had consensual sex in her home under the influence of alcohol, and possibly drugs, before he killed her.

She was strangled in the early hours of Friday, Creazzo said, but the autopsy revealed that she had two fractures to her skull — injuries that would also have proved fatal.

During a long interrogation that ended at 4.00 a.m. local time, Tidianee had “substantially admitted” the prosecutors’ reconstruction of events, Creazzo said.

Tidianee and his lawyers have not made any public comment but Italian media said he told police he had not meant to kill Olsen, but that she had fallen during a row.

Creazzo did not give Tidianee’s age but said he was born in 1988 and had arrived in Italy illegally a few months ago to join his brother who has been living in the country for some time.
