DNA Technician

Wendy is a DNA Technician and worked in San Fransisco (Lab where Sara Sidle came from) for a time before moving to Las Vegas to take the DNA tech position. In the Season 7 episode Lab Rats she helps Hodges investigate the case of The miniature killer. The two characters have an ongoing rivalry. Hodges complains that Simms tries to take over everything and thinks she's "too cool" for the lab. Simms insults Hodges by calling him "freakboy" and "loser" but praises his investigation methods. Wendy is apparently something of a klutz and has a reputation for being clumsy around work. In season8 it's revealed that she is a huge Trkkie fan (Star Trek) & once performed in a horror movie to earn extra cash.

In season 8 she seemed to show more of an interest in perhaps becoming a CSI & working out in the field.

In season nine she has made many more appearances in the episodes, and appears to now be in the regular cast. She has tentatively striking up a friendship and mentoring role with the new hire Dr Raymund Langston, as she guides him through some of the processing techniques he needs to learn.

In season 10 the 'Wedges' relationship between her & the character David Hodges was strongly hinted at again, but Hodges refused to take it any further, but Wendy planted a kiss on Davids lips in an episode.

Toxicology Technician

1st appearance as a suspect in 5.14 Unbearable (In the secondary kodiak bear case)

Henry is the toxicology specialist of the Las Vegas Forensics Laboratory, who mainly deals with identifying toxic substances which have undergone human consumption. He has an impressive knowledge of lethal substances, including, but not limited to: illegal drugs, alcoholic beverages, poisons, and hazardous gases (such as carbon dioxide). He constantly exhibits a thorough understanding of the toxins' properties and effects. He originally worked for days (as he mentions in the episode Iced) but kept 'getting moved around' by Ecklie. In the later seasons he is seen more frequently working graveyard, so it can be assumed he's acquired a permanent position there. In the episode Lab Rats he has a prominent role and an appreciable amount of screen time as opposed to his previous, short-lived appearances. Wendy refers to him as one of Hodges' "lemmings". It is construed that Hodges knows a fair deal of information about Henry's personal life.

In season 9 he has played a more active role in many more episodes,
with interactions with Catherine Willows mainly.

Hodges position in the lab? whether he's just the trace tech, or training to be a CSI? or maybe even multi tasking? he doesn't seem to have appeared to have had much training to be going out in the field like he has, so what is he Lab tech part time CSI?
