Police are trying to determine why a former pastor from the Houston area fatally shot his wife and 11-year-old son, drove to San Marcos and tried to strangle his daughter before killing himself.
Richard Logan, 53, killed 48-year-old Diana Logan and their son, Aaron, at their home in Sugar Land on Tuesday, police said. He then drove about 160 miles (260 kilometers) to San Marcos, where his adult daughter attends college, and attempted to strangle her, police said.
"We're not sure why he disengaged and left," said Sugar Land police spokesman Doug Adolph.
Logan then shot himself at TAS Environmental Service, a consulting company, just south of San Marcos. Police at the scene recovered the same gun used to kill Logan's wife and son. Police didn't immediately know what connection, if any, Logan had with the business.
An investigation is ongoing.
Rodolph said detectives haven't identified Logan's motive in the killings.
The former pastor founded Attack Poverty, a nonprofit that connects people with jobs, education, medical care and spiritual outlets in underserved communities. He posted frequently on social media about his nonprofit's initiatives and his family.

The Logans' deaths shook their community.
"I think I share with everybody who knew the Logans a real sense of shock that this was so unpredictable," Pastor Patrick Kelley at River Pointe Church said at a news conference Wednesday. "And we knew the Logans very very well, and something like this . is just something you cannot predict or foresee."
The nonprofit Logan ran issued a statement, reiterating the shock waves the family's deaths have sent through its community.
"The Attack Poverty family is in shock to learn of the tragedy involving our Chief Executive Officer, Richard Logan, and his family. We are cooperating with investigators and waiting for more information as we try to process this loss with our staff, volunteers and community."
A memorial service will be held at River Pointe Church in Richmond, outside of Houston, Monday at 2 p.m.
