An Indian dental student, who was found dead in the US city of Albany in California State, was shot in the head but there were no signs of a forced entry into her apartment, police have said.
Investigators said the 37-year-old was shot to death at her San Francisco Bay Area apartment hours after attending afternoon prayer services at a Sikh temple.
The body of Randhir Kaur was discovered by her cousin in her Kains Avenue apartment at about 4pm on March 8 after University of California San Francisco officials became concerned about her well-being.
Kaur was a student at the UC San Francisco and had enrolled in the International Dentist Programme with an anticipated June 2016 graduation date.
"She was shot once in the head inside her apartment," police said.
Detectives found no signs of forced entry into her apartment or foul play. Kaur's car, a 1999 Toyota, was found parked and locked at her residence, police said.
Despite a week-long focus on evidence collection and pursuing investigative leads no arrests have been made and no suspects have been identified, they added.
On Monday, police found personal items belonging to Kaur inside a trash receptacle in the 5200 block of Panama Avenue in Richmond, roughly 2 miles (3.2 kilometers) away from Kaur's apartment.
Experts from the Alameda County sheriff's crime laboratory have been called to assist in the investigation, which police said is a standard practice for any homicide in the city.
Two additional investigators have been assigned to the case, bringing the total number of full-time investigators to 6, along with several part-time personnel, police said.
Police are asking for the public's help, particularly those who live on or frequent Kains Avenue in Albany or Panama Avenue in Richmond, in providing any information about suspicious people or activities on March 8 in those areas.
