Police found the dismembered body of 77-year old Johanna Christy buried in a shallow grave in her own her backyard Tuesday morning, on the 3800 block of Bentwood.

Now, police are questioning her grandson, 27-year old David Christy, in connection with her death.

Kiii News Reporter Michael Gibson went Live from the victims home with the details of this gruesome investigation.

Police arrived at the Christy home on Bentwood to check on the 77-year old woman after receiving a call from the victim's relatives in San Antonio, saying they had not heard from her in a while, just after 5:30 p.m. Monday night. When they arrived, David Christy, the victim's grandson, took off on foot.

A neighbor said that her son had seen Christy running off and yelled at him. Police eventually caught up with Christy at a nearby apartment complex at around 8:30 p.m. According to police, Christy fought with officers and was arrested for assaulting an officer and for evading and resisting arrest.

The same neighbor had said that the body may have been buried early Sunday morning, and that a detective told her that, from looking at the remains, the grandmother was probably killed two days ago.

That time period would match up with a text message sent at 4:59 a.m. Sunday from the neighbor to her son, telling him that his dog was barking at something in the back. She believes the dog was going crazy because that was when the 77-year old woman was being buried.

"They still haven't determined the cause of death, so that's something the detectives are very interested in, to see how they proceed in this investigation," said Senior Officer Kirk Stowers of the Corpus Christi Police Department. "It really is the starting point to establish a timeline, a sequence of events, so that we can hold somebody accountable; because with a crime like this, we're certainly interested in being very careful with our actions to make sure the correct person is held accountable."

Residents said that Johanna Christy kept to herself and lived in the home for more than five years. One neighbor said crime of any kind did not happen on this typical southside street.

However, many of the residents in that neighborhood said that they knew something was wrong when they saw Christy's cane still inside her car. The senior never left without it.

"I've always felt real safe, but I have to admit, I have two nieces and my daughter, and we don't let them outside," neighbor Liza Hitt said. "Even prior to this happening."

"She was a very sweet woman," neighbor Katie Christiansen said. "It is sad what happened to her. I mean, it is very unfortunate."
