Kansas City police are investigating the stabbing death of a 27-year-old mother of four young children.

Police say Deandrea Vine was killed Saturday in the yard of the southeast Kansas City home where she lived. A cousin discovered her body about 4 a.m. Saturday.

Investigators have not released any information about a possible suspect.

The Kansas City Star reports Vine's family said she battled learning disabilities and epilepsy while struggling to raise her children, who ranged in age from 7 to 21 months.

Her mother, Kelly Jackson, says the father of Vine's children committed suicide about a year ago. Vine was working at Walmart while she and her children lived with Vine's mother and grandmother.

The family is asking anyone with information on the killing to call police.
