A far North Dallas grandmother was found dead in her apartment when her two daughters went to check on her Tuesday afternoon.
Police are investigating the death of 50-year-old Stephanie Cathcart as a homicide.
Her two daughters went to her apartment in the 15200 block of Preston Road at about 2:15 p.m. after she didn't show up to work Tuesday morning and did not return their phone calls.
They called police when she didn't answer the door, and officers broke down the door.
“I just want to know why,” said Shirley Jones, Cathcart’s mother.
Cathcart was a mother of four and a grandmother of 13.

“It’s very hard to understand," said Cathcart’s daughter, Latoya Jones. "I don't understand. It’s got my mind going a million and one ways."
Relatives said Cathcart recently told her husband, Calvin, she wanted a divorce. Family members said they have not been able to reach him all day.
“That's why it’s so important," said Sharon Aycock, Stephanie Cathcart’s sister. "If he had nothing to do with this, to clear his name -- just find it in his heart and come let your family know what happened."
Dallas police said Calvin Cathcart is a person of interest in the case. His abandoned car was found in South Dallas overnight Tuesday.
Stephanie Cathcart's family said it is filled with questions and unimaginable sorrow.
“She didn't deserve this," her mother said. "She’s a very loving woman, and it hurts so bad to know someone so loving could have been done like that."
Dallas police have released little information about the case.
Cathcart’s relatives said her Cadillac was missing from the parking lot and that police found it abandoned in South Dallas.
