DALLAS(CBS11) – There is still a mystery about the deaths of three people killed in an SUV crash in Dallas Wednesday. Family members of two passengers say they don’t know the driver, or how she knew their loved ones.

Thursday afternoon a security fence went up around the apartment where the wreck ended. Police say the SUV was going so fast it hit a parked car before both plowed into the apartment.

Family members of Paul Maltos remembered him fondly Thursday. “Yesterday before I went to work I gave him a kiss,” Pennie Zavala told CBS 11 News, saying the kiss for her father was a morning ritual.

She continued to live with 93-year-old Paul Maltos even after he remarried a few years back. Maltos and wife Evelina were passengers in the crash and were killed on impact. So was the driver, Lucinda Rosas De Esparza.

Neither family claims to know the other or where the three were going. “Sometimes you don’t have all the answers. Sometimes you don’t need all of them, either,” Zavala said.

She wonders if Esparza was the stranger who showed up at their door recently claiming to be from Maltos’ home town in Mexico. Esparza’s son tells CBS 11 News that his family just as much in the dark as everyone else.

Meantime the families prepare for funerals.

“I want to remember him in a good way, not in the tragedy that happened,” Zavala said adding, “He just went on a cruise, he just remarried and he was full of life. He loved to dance and laugh and we’re just going to miss him.”

Maltos’ grandson, Celso Cortez, laughs, too, at the thought of a bet the two made as they watched the recent Mayweather- Pacquiao prize fight. “He’s like, ‘C’mon, get him!’ He puts his hands up, ‘C’mon, you can box him.'”

Great-granddaughter Estrella Hernandez added, “(Great) Grandpa was always, ‘C’mon, party. Let’s have a cookout.’ That’s what I remember, a cookout and fire up the grills. ”

Dallas police have not yet revealed what investigators think may have happened. They are still awaiting autopsies, police told CBS 11 News.
