Former security guard Rajkumar Singh showed perfumer Monika Ghurde three porn clips before raping and killing her in cold blood, the accused confessed during police interrogation on Tuesday.
Ms Ghurde's body was found tied to her bed at her rented apartment in Goa's Sangolda village on October 5.
The accused Rajkumar Singh, 21, arrested from a Bengaluru hotel on October 8, was traced by police through Ms Ghurde's ATM card, which he used at several locations.
"The accused has confessed to the crime. He has told the Investigating Officer that for two days he took refuge on the terrace of the building where Monica lived before forcibly entering her flat on October 5 evening," Deputy Inspector General of Police Vimal Gupta told reporters.
In more chilling details, which police said was revealed during his interrogation, Rajkumar, after forcefully entering the house, overpowered Ms Ghurde at knife point and when she lost consciousness, tied her to a bed.
After ensuring that she was helpless, he demanded money.
"She told Singh to take whatever money was there in her purse. He found Rs 4,000, which Singh told her was not enough for him," Gupta said, adding that when Singh demanded more, Ghurde told him to take her ATM card and gave him the PIN.
Singh took her cellphone to prevent her from alerting anyone and forced her to give him the cellphone's password. "Once he got the password, he forced her to watch three porn clips," the DIG said.
Gupta said Singh released Ghurde's legs and raped her. "We will add Section 376 (rape) IPC to the case," he added.
He later strangled the victim and then smothered her face with a pillow to death.
He also took Ms Gurde's phone, some cash and her ATM cards.
The DIG said the police has clinching evidence as the suspect shaved at Ghurde's flat. "We have recovered hair from the spot," he said and added that a DNA analysis would be done.
Police said Rajkumar, a native of Punjab's Bhatinda was vengeful towards Ms Ghurde after he had lost his job as the complex's security guard in July, following complaints from Ms Ghurde and other residents.
"The accused was attracted towards Monica since the day she inquired about availability of a flat in the complex and later followed her movements when she started residing there. After his duty as a security guard, he would wash cars of the residents, including that of Monica," the Mr Gupta said.
Ms Ghurde's lost umbrella was found on him among other charges.
Mr Gupta said the security agency who employed Rajkumar also refused his two month's salary amounting to Rs. 22,000.
The accused planned the crime after not being able to persuade Ms Ghurde to take her complaint back or find another job, the officer said.
Rajkumar was brought to Goa on transit remand and produced in a court of a Judicial Magistrate on Tuesday which has reminded him to a seven days in police custody.
