Today, several agencies joined Mission police in the search for 70 year-old Modesto de la Rosa.
De la Rosa went missing last Saturday, and was last seen near a canal off 2 Mile Line and Los Ebanos Road in Mission.
Horses, hounds and a dive team were used to make sure no area went unchecked.
De la Rosa TMs family members were at headquarters of the search hoping to hear news, whether it be good or bad.
"Whatever news, whether it TMs good news or bad news, we are just waiting, we just want to see him, daughter San Juanita de la Rosa said.
Juanita told Action 4 the search for her father has taken a toll on her family.
"We can TMt sleep, no we can TMt even eat, it TMs really hard," Juanita said.
The Texas Criminal Justice K-9 unit was enlisted to track any trails that could lead to de la Rosa.
Mission police interim-chief Robert Dominguez said his department is doing all that they can to find him.
"These type of operations, of course, are very long and obviously tedious, however that TMs what we are here for," Dominguez said.
Family members say de la Rosa would walk along 2 Mile Line daily and sometimes drink alcohol, a reason the Mission Fire Department TMs dive team was called in to drag a nearby canal where he was last spotted.
"At the time we don TMt know if he was intoxicated or at what time he would have purchased any alcohol and became intoxicated and fell in the water," Dominguez said.
Although they are checking the canal, police and family members believe he is still alive.
"We've gotten several tips that they have seen him after that so that TMs why we are not losing hope that he's alive," Dominguez said.
Police say the search overhaul will cost several thousand dollars, but it TMs a price tag they say is worth paying to bring a loved one home.
