Dallas police released a new surveillance video they hope will help them find a person of interest in the case of a Lake Highlands woman killed in her home.
Dallas police want the public's help in finding several people seen at various stores using the credit cards of a 79-year-old woman killed in her East Dallas home last week.
Avanell Cowgill's daughter asked police on Saturday to check on her. Officers went to the home in the 11300 block of Earlywood Drive in East Dallas and found the back door open and Cowgill dead inside the home.
Cowgill left church at approximately 3:30 p.m. Thursday. Police said she went to a store, went home and may have been killed that night.
On Tuesday, Dallas homicide detectives released photos of two people seen at various stores on Friday, using Cowgill's credit cards.
Dallas police released new video in the case on Thursday that they said shows a man shopping at a Walmart on March 8 before he used Cowgill's credit card to pay for the purchases.
The first person is a white man who is taller than 6 feet and weighs about 250 pounds. Police said he changes his appearance from one store to another and tries to avoid store security cameras.
In one photo, he is seen wearing a blue jeans, white shoes, a gray windbreaker and a baseball cap with a "B" on the front. Police say the same man was seen at a second store wearing blue jeans, white shoes, a brown work jacket with a hood and a black-and-red baseball cap with a "B" on the front.
The second person is a white man who is 5 feet 8 inches tall and weighs about 160 pounds. He was seen wearing a red, yellow and black horizontal striped shirt.
