SPRING, Texas (KIAH) — A Spring man who allegedly shot his wife and her grandmother is dead from a self-inflicted gunshot wound after a chase in north Texas, authorities said.

The Montgomery County Sheriff’s Office said that they were looking for Obinna Igbokwe, 41, who allegedly took his baby son, Mansa Igbokwe, after an argument with the mother over custody of the child.

The incident started when Montgomery County deputies were called to the 30120 block of Aldine Westfield Road and found two victims who were shot in the head. One victim, Tangela Igbokwe, Mansa’s mother, was taken to a local hospital and is listed in critical condition.

Another victim, identified as Linda Larkins, Tangela’s grandmother, was pronounced dead at the scene.

Investigators with the Montgomery County Sheriff’s Homicide/Violent Crimes Unit say that they believe Obinna Igbokwe is suspected of shooting the two victims and taking the child.

Early Thursday morning around midnight, police in Corsicana told Montgomery County authorities that Mansa was in their care after a man they believe was the suspect dropped off the child in a car seat at a local hotel. He told the hotel workers he would be right back, but never returned, police said.

Then a little after 1 a.m., police officers in Ennis located Igbokwe’s Honda Accord and an attempt to stop it led to a pursuit. The car pulled into a parking lot, then officers heard a single gunshot from Igbokwe’s car, police said. After officers began life-saving measures, Igbokwe was transported to a Dallas hospital, where he was pronounced dead at 5:20 a.m.

Authorities issued an Amber Alert for Mansa Igbokwe but was cancelled early Thursday morning as authorities said the child was found and is now with a family member.

The investigation is being completed across multiple jurisdictions and involves the Corsicana Police Department, Ennis Police Department, Ellis County Sheriff’s Office, and the Montgomery County Sheriff’s Office.
