Man Charged After Engineer Killed Minutes After Visiting His Mother

A Texas engineer was killed in a neighborhood park shortly after visiting his elderly mother at a nearby nursing home, and police later charged a 26-year-old man in what investigators described as an apparently random attack. Andrew James Wimsatt, 62, was found dead at Chandler Creek Park in Round Rock on Sept. 7.

Williamson County sheriff’s deputies were called to the park shortly after 11 a.m. after a woman found Wimsatt near a bench and called 911. Authorities said Wimsatt and the man later charged in his death did not know one another.

Wimsatt had visited his mother before stopping at the park, according to reporting from People. That ordinary family visit became the last known part of his morning before the crime.

Surveillance Video Gave Detectives a Timeline

Investigators obtained video from the Chandler Creek homeowners association and other locations near the park. The footage helped detectives follow the movements of a man they later identified as Benedict Chinedu Ogbodiegwu Jr.

Police said the video showed Wimsatt seated on a park bench before the attack and showed the suspect leaving afterward. Investigators then used additional footage to continue tracing him through the area.

A palm print recovered near the park and other evidence also helped connect Ogbodiegwu to the location, according to reporting based on the arrest affidavit.

Authorities searched Ogbodiegwu’s residence about a mile away. Investigators reported recovering clothing and a knife they believed were connected to the case.

Police Arrested Him the Same Day

The Williamson County Sheriff’s Office took Ogbodiegwu into custody and charged him with murder. Court records reported by local media also described a theft-related charge.

The murder charge is an allegation. Ogbodiegwu has not been convicted, and the evidence against him will have to be tested in court.

Investigators said preliminary information indicated the attack was not premeditated and that there was no known relationship between Wimsatt and Ogbodiegwu. Authorities had not publicly identified a motive in the approved reporting used for this article.

Wimsatt worked as a civil engineer and researcher and had professional ties to the Texas transportation field. People reported that he had worked with the Texas A&M Transportation Institute.

A Familiar Stop Became the Center of the Case

The setting has made the case especially difficult for people who use the neighborhood park. Wimsatt was not at an isolated location or involved in a known dispute. He had stopped at a public park during the morning after seeing his mother.

The sheriff’s office announced his identity two days later and extended condolences to his family and loved ones while emphasizing that the investigation remained active.

The timing gives the case its strongest human detail. Wimsatt’s final morning included something entirely ordinary: visiting an elderly parent. Minutes later, a woman walking through the park found him and called for help.

Investigators were able to move quickly from that discovery to surveillance footage, physical evidence and an arrest. The legal case will now determine whether prosecutors can prove that Ogbodiegwu was responsible.

For Wimsatt’s family, the arrest provides a defendant and a court process. It does not change the suddenness of the loss: a 62-year-old engineer left a visit with his mother, stopped at a familiar public park and never returned home.

The investigation also shows how quickly ordinary surveillance systems can become central after a crime in a public place. In this case, detectives said video from the neighborhood helped establish a sequence of movements that led them toward a suspect within hours. That evidence will now be reviewed through the criminal court process alongside the other material collected by investigators.
