Here some things to know about the family of the suspects in the San Bernardino massacre that left 14 dead and 21 wounded.
Where they lived
Suspects Syed Rizwan Farook, 28, and his wife, Tashfeen Malik, 29, lived with their 6-month-old daughter and his mother in a town house they rented in Redlands, a city neighboring San Bernardino.
His mother, Rafia Sultana Farook, apparently moved in with him after selling the family's house in Riverside earlier this year for $290,000, according to public records.
Rafia Farook and her husband were divorced this year and she had been living in the house alone, according to the real estate agent who sold the house in June.
She said she planned to move in with a son to be closer to family and a mosque in nearby Corona, Linda Holmes said.
Farook's brother, Raheel, lives in Corona with his wife, and their 1-year-old daughter.
Syed Farook, father of the clan, is also believed to live there, according to court papers.
Parents of the gunman
Syed Farook, 66, and Rafia Farook, 62, were married on New Year's Day in 1982, according to court records.
He was born in Pakistan and she was born in India.
Syed Farook had been a truck driver and she worked since 2003 in the billing department of Kaiser Permanente.
The couple had four children — two girls and two boys.
Efforts to reach family members for comment at their homes and by phone have been unsuccessful.
Problems at home
Rafia Farook first filed for divorce in 2006, citing irreconcilable differences and accusing her husband of being an abusive alcoholic.
She said he attacked her in front of their children, dropped a TV on her and pushed her toward a car, according to divorce records. She said a daughter intervened to save her.
The case was eventually dissolved and she filed for divorce again in 2008 and again in 2012. She also filed for restraining orders several times.
In her final divorce filing, she listed Valentine's Day last year as the date of separation. A judge approved the split this year.
A neighbor of Raheel Farook said that Syed Farook, the father, is talkative and often visits him as he works on classic cars in the garage. Dane Adams said the father said he was divorced and discussed his family.
Parents of the female shooter
Malik was from the Pakistan town of Karor Lal Esan, 280 miles southwest of capital of Islamabad.
She traveled to Saudi Arabia twice to visit family. Her father, Gulzar Ahmed Malik, who has been a resident in the kingdom since the early 1980s, the Saudi Interior Ministry said.
Gulzar Ahmed Malik, reached in Jiddah, Saudi Arabia, condemned his daughter's actions and said he is "very, very sad. ... I am in such pain that I cannot even describe it."
Sister of gunman
Saira Khan, 32, the older sister of shooter Syed Farook, is seeking to adopt the baby girl he and his wife left with his mother when they launched their attack.
The child remains in the custody of San Bernardino County Child Protective Services and a hearing has been scheduled next month.
Khan's husband, Farhan Khan, spoke for the family the night of the shooting.
He condemned the violence, said he was in shock and had "absolutely no idea" why his brother-in-law "would do this."
Brother of gunman
Raheel Farook, 30, served in the Navy from 2003 to 2007 and earned two Global War on Terrorism medals, among other awards.
He married a Russian divorcee, Tatiana Gigliotti, 31, four years ago in a ceremony witnessed by his brother and Enrique Marquez, a man who grew up next door to the family in Riverside, according to marriage records.
The couple has a 1-year-old daughter.
Gun buyer, relative by marriage
Marquez, 24, a former security guard and longtime friend of Syed Rizwan Farook, legally bought the assault rifles used in the rampage, but police have not revealed how they got in the hands of the two shooters.
Investigators are also looking into whether Marquez and Farook planned — and then aborted — an attack in 2012.
Marquez became a Farook family member when he married Tatiana Farook's sister, Mariya Chernykh, 25, last year, according to Riverside County records.
Raheel and Tatiana Farook were witnesses at the ceremony.
He and Raheel Farook are now brothers-in-law.
The Russian sisters both came to the U.S. on visas for work or student exchanges.
Marquez's security license expired last year and he was recently fired from a job at Wal-Mart.
He checked into a mental health facility after the shootings and has been interviewed by federal authorities. He has not been charged with any crime.
