Police on Tuesday took Assam native Ameerul Islam to law student Jisha's home in Perumbavoor in Ernakulam district of Kerala to recreate the murder scene.
The 27-year-old Dalit woman was found dead on April 28 at her home by her mother Rajeshwari, a casual labourer.
Her body bore injuries that led to suspicion that she was raped before her murder. Police later arrested Islam in the case.
After Islam was taken to Jisha's home on Tuesday morning, he allegedly told police how he committed the crime and how he escaped from the spot.
Police said though the murder case has been cracked, a few missing links in the case needed to be tied up. It's still not clear if Islam acted alone since he has been changing his statements, police said.
The police custody of Islam will end on Thursday.

Meanwhile, the mother and sister of Jisha told police on Tuesday that they had not seen the accused ever before the crime.
"We both have not seen him before. When we confronted him as to why he murdered Jisha, he said it happened just like that," Jisha's elder sister told reporters here.
After the Pinarayi Vijayan government took over on May 25, it set up a new team to probe the murder. Police arrested Islam on June 16 from Palakkad border in Tamil Nadu.
