A twin-engine plane crashed near Kerrville Municipal Airport in Texas on Monday, killing all six people onboard the aircraft.

The incident took place around 9 a.m. local time (10 a.m. EDT) as a Beechcraft BE58 was preparing to make a landing at the airport, about 70 miles northwest of San Antonio, after departing from West Houston Airport outside Houston, Federal Aviation Administration (FAA) spokesman Lynn Lunsford said.

The wreckage of the plane was discovered six miles northwest of the Kerrville Municipal airport. Photos from the scene showed the tail number of the plane was N501CE.

Sgt. Orlando Moreno, a spokesman for the Texas Department of Public Safety, said six people, including the pilot and five passengers, were dead. The victims were identified as Jeffery Carl Weiss, 65, Stuart Roben Kensinger, 55, Angela Webb Kensinger, 54, Mark Damien Scioneaux, 58, Scott Reagan Miller, 55, and Marc Tellepsen, 45. All of them were from Houston.

Weiss, who was piloting the doomed aircraft on the day, co-owned the plane with Charles Morina of Dallas. He was the senior vice president for investments at Raymond James and Associates in Houston. He was known for being a philanthropist who volunteered to transport sick people from remote regions to Texas hospitals for Angel Flight South Central – a non-profit organization which arranges air transportation for medical and humanitarian purposes through a network of volunteer pilots. He also supported charities for children with special needs or who suffered abuse, Houston Chronicle reported.

Tellepsen was the owner of Tellepsen Landscaping, a landscape architect firm in Houston. Scioneaux worked at Tellepsen Landscaping and was the husband of Houston Ballet artistic director Stanton Welch, ABC13 reported.

The Tellepsen family issued the following the statement Monday: “The family of Marc Tellepsen is extremely grateful for the outpouring of support from our friends, family and fellow Houstonians at this incredibly difficult time. We hope you understand our need for privacy as we grieve for the loss of our husband, father, beloved family member and friend.”

They also added that the plane was carrying Tellepsen and Scioneaux on a trip to survey some property when the crash happened. The site where the wreckage was discovered belonged to a private ranch. Robert Hurt, a former pilot who lived in the area, told My San Antonio that the aircraft might have strayed off its scheduled path to look at the property. "I don't know why they were this far west," he said.

Not much else was known about the other victims who died in the crash.

The cause of the crash was not determined yet. National Weather Service meteorologist Cory Van Pelt told USA Today that there was no rain around the area at the time of the crash so the weather was not a probable cause of the crash.
